Does Mounjaro get Used Up?
I’ve been curious if Mounjaro can get “used up” during the week. I’ve had a couple of situations where I wonder if I’ve run it dry, for lack of a better term.
I take this (15mg) for T2D glucose control and wear a CGM.
I shoot up on Thursdays.
Normally my glucose is very well regulated for the entire week if I behave well with my food choices.
Sometimes, though, I’ll have a day when I don’t make good choices and it seems like the effects last much longer than they should.
I took my shot last Thursday, July 2nd. On the 4th, we had a party at my home and I drank a six pack of 6% and ate quite a bit of high-carb foods. I very rarely drink. I think the last time was around April when I had a margarita at a Mexican restaurant.
Needless to say, my glucose went nuts. I expected that, but I figured that it would just be one day so it wasn’t a big deal.
My glucose levels stayed nuts all the way until this morning after I took my latest shot last night.
Between Saturday and Thursday, I was watching my glucose swing wildly up and down for no apparent reason, even while maintaining my normal diet.
It’s almost like my Saturday blowout used up all the Mounjaro in my system so I didn’t get my glucose back under control until I refilled the “tank”.
Has anyone else noticed anything like this?
