Got my second Moderna shot this Sunday. OMG. Feel miserable. Like I have the flu. Aches and pains everywhere. Thankfully no fever and no BG problems at all. So exhausted that I fell asleep while talking with my husband! 
Right in the middle of a sentence (so he says). Took a nap yesterday afternoon that lasted 6 hours! I know it will pass though, so I am not really concerned. I went into it knowing that this would most likely happen. My biggest joy is that I dont have any BG reactions at all. I hate when I get sick and I have to deal with that on top of it.
BTW: does anyone else spike from eating bananas? I cant seem to bolus properly for them, and I dont want to give them up. I always have to give myself a correction bolus about 1.5 hours after finish eating one.
