I think the peanutbutter was making everything else much worse. The fact that the day I spent doubled over in pain and puking started with bolting my breakfast and then since I was too sick for the stuff the next day I wasn't sick, and then ate peanutbutter and was increasingly ill for a few more days until I had leftover pumpkin pie, and then ate breakfast out, and wasn't sick, and haven't eaten the stuff since and have been increasingly fine... even Metformin, which was a problem long before the peanutbutter, isn't making me have stomach cramps.
And I took two Ibuprophen when I put up that post and have had no negative gastric stuff, so I think whatever was hurt is healing. I have taken Aspirin at bedtime every night which was never a problem, but not anything during the day. Today I have to, I hurt too much otherwise. I think it was walking on ice all last week, over-stressed my joints keeping my weight straight over them so I didn't fall.
Sounds like you have an allergy for sure !
Any other symptoms ?
Rash, flushing, itching ?
