True… just as they may be vastly inferior for a lot of people that are still using them… which is unfortunate… that’s why I’m glad to see people trying everything… anyway I don’t want to turn your thread into a debate about the pros and cons of pumping, let’s just see how well this can work! ---

Not trying too either except the one observation I have after trying MDI for the last couple of months or so if that there are definitely bolus advantages to the pump that MDI can’t match. I’m sticking with MDI for now, but I hate that I can’t square wave, bolus discreetly, or have pre-programmed carb ratios etc. It can be really annoying sometimes! ---

I just ordered some more 8 mm needles to use with my Tresiba pen. I used a 4 mm one to do my injection (the pen came with some needles), and I think that’s why it felt burny and stingy. I prefer the 8 mm needles. Except for IM with Fiasp, then I use 12 mm ones. 🙂 ---

They stopped making Levemir penfills in the US though so there’s something more behind this. Also I think they sell Tresiba penfills in Europe. ---

> [@docslotnick](#): > > It’s because Tresiba comes in U100 and U200. It would be too confusing for non FUD people. Yeah but if you were @eric you would just save some old pen cartridges and fill them with tresiba like this… > [@Filling your own pens](https://forum.fudiabetes.org/t/filling-your-own-pens/1111): > > I’ve been filling my own pens for a while. Why? Not all the disposable pens are refillable Re-filling from a vial is cheaper than buying disposable pens. You can fill them with any amount you want. Rather than having 300 ml sitting outside for months (that’s how long it would take me to get through some of the basal ones), or always having to go into the refrigerator to get one out, I can just fill it with a week’s supply at a time. Only one week’s worth stays outside, the rest of it stays in… ---

> [@Jen](#): > > . I think many people in the US have never seen the reusable pens, since I don’t think they’re available there, @Jen I’m in the US (well in Texas anyway ) and I’ve been using a novo- pen metal pen since about 1998. I agree that the plastic Tresiba pen pretty much sucks, but the stuff inside it is pretty darned good. ---

@jen - I am sure there is a Russian Pharmacy that will ship to you 😆 ![image](https://canada1.discourse-cdn.com/flex030/uploads/fudiabetes/original/2X/2/2f3af4b033f33a721ab3b7dadfb84e06cb19f149.jpg) ---

Interesting… Dropping rapidly (5.2 mmol/L to 4.3 mmol/L in 10 minutes, unfortunately CGM is in warmup) at the moment. I did take Fiasp 2 1/2 hours ago to cover some carbs. Didn’t spike at all, just held steady and now dropping. So either Tresiba dose is too high or I’ll need to correct my ratios with the change. ---

And I’m now 3.9 mmol/L so will officially treat. 🙂 ---

Did you need to change your ratios with the switch, @Sam? ---

If so then only gradually over time… my ratios seem to be constantly evolving and I didn’t detect any differences to those trends when I switched to tresiba ---

Well it might be different coming off a pump… it’s far more cloudy what’s actually basal and what’s actually bolus when it’s coming from the same place ---

> [@Sam](#): > > it’s far more cloudy what’s actually basal and what’s actually bolus when it’s coming from the same place I don’t think so… To me it’s not murky, anyway. Unless you’re talking about NPH, in which case yes, it’s very unclear about what’s being covered by NPH versus other insulins… But on a pump, basal is either insulin that holds you steady between meals or insulin that the pump delivers automatically, while bolus is either insulin used to cover food and high BG or insulin that you have to manually program in to deliver. I do imagine with some of the automated systems where basal rate is adjusted to cover high BG, it’ll become murky. But with a current-day, manual-only pump, it’s not. ---

Yeah but when it’s absorbing from the same infusion site, how your brain’s thought process is conceptualizing it is not always the same as the function it’s actually accomplishing… I actually thought of a mock-up today… I was gonna make a YouTube video with it… big soup pan in the sink with the faucet trickling into it (basal dose). Then at random intervals I throw an extra cup of water into the same pot (bolus). after it’s in there which is basal and which is bolus? Doesn’t matter what it’s intention was… take a scoop out and it’s all the same ---

> [@Sam](#): > > Yeah but when it’s absorbing from the same infusion site, how your brain’s thought process is conceptualizing it is not always the same as the function it’s actually accomplishing… But does that matter? Insulin is released from “all one place” in the pancreas, and in the body there is no distinction between basal and bolus. So it’s not like your body cares where the insulin is coming from or what it’s called. With MDI, basal is one type of insulin that keeps your blood sugar steady between meals and bolus is another type of insulin that’s taken to cover food or high BG. On a pump, basal is a pre-programmed background dose of insulin (that is tested by fasting through meals) that keeps your blood sugar steady between meals and bolus is insulin that’s manually programmed in to cover food or high BG. In the end, those two things are accomplishing the same task and are conceptuatlized the same, even though their delivery is different. The only reason we have “basal” and “bolus” is so we can manage diabetes better. Those terms weren’t even around when I was diagnosed. ---

well in my opinion it matters tremendously… yeah in the natural correctly functioning metabolism this stuff all happens automatically, here we are trying to reproduce those processes through two mechanisms… In my opinion keeping them completely distinct from each other makes it extremely easy to identify where either one is lacking… but combining them has some advantages it can also create a very confusing situation where one doesn’t know what’s truly doing what… [Previous page](https://forum.fudiabetes.org/t/tresiba-experiment/2910.md?page=3) [Next page](https://forum.fudiabetes.org/t/tresiba-experiment/2910.md?page=5)
