> [@Nickyghaleb](#): > > I’m a little behind… but I swear I’ve done a bunch of experiments over the last 6 months to understand auto mode that included waking and not having coffee… I don’t get that rise. I really don’t. I think. 😉 So waking up is not a problem in the morning, only coffee? > [@Nickyghaleb](#): > > The thing I haven’t done yet, , is try black coffee … it makes me sad to think of, the taste, but I suppose that might be the logical next experiment? I could do the waking one, too. Coffee cream adds a little bit of carbs to the mix, but not very much. Not as much as the way you have described it. There are certain things in coffee that could lead to a BG rise. It doesn’t affect everyone. If it affects you, then just plan for it accordingly. ---

> [@Eric](#): > > Please verify it’s the coffee and not the combo of coffee AND waking up. Have you done that already? Tea at night is horrible for us. I hate to say no to anything food related. But it really was just more than I could handle. I asked if it would be okay if we stopped the nighttime tea. ☹ ---

Wouldn’t that keep her up at night anyway? I don’t let my non-D son drink tea at night! ---

No. Nothing keeps her up at night. 5 minutes after she lies down - out cold. And then I have to deal with the BG fallout. lol Anyway - not trying to hijack. 🙂 My point that I agree with a previous post that caffeine seems to be different for different people. For us, it would appear that caffeine causes an unreasonably large rise in BG that definitely is distinct from the morning rise. ---

Since you said “Tea **at night** is horrible for us”, I am curious, is tea at other times not as significant? Like is it a combination of tea and nighttime? Is it a combination of tea and a response to dinner carbs? So many things to think about for stuff like this. ---

> [@Thomas](#): > > For us, it would appear that caffeine causes an unreasonably large rise in BG that definitely is distinct from the morning rise. I have a terrible habit of drinking coffee way past the morning hours. I have to bolus for it all day long. There are times I can use it to offset a low. Like today! I accidentally bolused 12 UNITS of insulin and only needed 2 cups of coffee to help me through the first couple of hours. Then a third… for a little extra time. And then at some point I just switched to cookies. So that I wouldn’t suffer a heart blowout. ---

I can put him in bed with me and try to get him to sleep and find him still awake in the morning. I have to drink caffeine at night to try to outlast him… ---

> [@Eric](#): > > So waking up is not a problem in the morning, only coffee? I have zero memory of ever getting up without coffee and not being able to figure out a high. In all of my experiments, I would decline steadily. I’d be happy to test it out, but I would be floored to see anything different. > [@Eric](#): > > Coffee cream adds a little bit of carbs to the mix, but not very much. Not as much as the way you have described it. And here’s the thing… I’ve been drinking coffee for probably 12 years? I’ve had it a lot of different ways—well, not black—- and i’ve always done approximately the same amount of insulin. I’ve done it with a splash of milk and a Splenda, with regular creamer, with sugar free creamer… so three different ways. 😃 The only time I ever had to really change how much I was doing was when I was in auto mode… I went from about 6 or 7 g per cup to 16 g per cup. It turns out it had nothing to do with the coffee— I was getting back some of my missed insulin from over night. ---

> [@Thomas](#): > > I agree with a previous post that caffeine seems to be different for different people. I read a lot of people saying it spikes them. I’ve always said it doesn’t have any effect on me, but I only drink coffee with breakfast, so it’s hard to know for sure. Coincidentally, just this morning I got up early to work. At 4 a.m.I was 4.5 (81). After two mugs of black coffee, no food, two hours later I’m 5.6 (100). [EDIT: 3.5 hours later, I’m still 5.6.] So a minor rise, and probably not one I’d ever bolus for. ---

I have seen one cup of tea send the BG over 250 in like 20 minutes. It is like WTF - was that spiked with glucagon? ---

> [@Eric](#): > > Since you said “Tea **at night** is horrible for us”, I am curious, is tea at other times not as significant? The tea spikes. Trying to deal with high BG for any reason at night is extremely difficult. It takes an unreasonable large amount of insulin. And dosing huge amounts of insulin at night is not something that I can reasonably then go to sleep afterwards. So it ends up being a few factors combined. ---

And dosing huge amounts of insulin at night is not something that I can reasonably then go to sleep afterwards. So it ends up being a few factors combined. I have a similar difference in how beer raises my BG late at night (not a huge spike, but enough to be noticed). In the evening with dinner, it does not really do much. But later at night, well after dinner, it has a much bigger effect. I know that it is a combination of beer and being a few hours after dinner and nighttime - because without all 3 of those things it doesn’t do anything. ---

_ **Thankfully** _ coffee has little, if any, affect on my BG. I usually have 3-4 good sized mugs of it each morning with cream and with a few drops of liquid Stevia. It’s so interesting how things impact each of us so differently. ---

> [@Millz](#): > > I usually have 3-4 good sized mugs of it each morning with cream and with a few drops of liquid Stevia. That’s awesome. And a little enviable. I can start at a blood sugar of a 40 and still hit the roof half way into my first cup of coffee. I sometimes have to sit and just watch my cup while I wait for my blood sugar to steady out enough to drink it, and SOMETIMES I bolus and wait but never get it. 😢 This could be the universe though… with an intervention of sorts. 🤔 ---

I drink hard core coffee…no unleaded for this self-declared coffee fiend (well really, coffee addict)! And my coffee doesn’t look like no stinking tea (no offense to all you tea lovers). 🙀 Proof: about 5 years ago, while visiting our daughter in Missoula, Montana, my husband and fell for coffee from a local place called Black Coffee Roasting Co. We still mail order our beans from there.
