Ive always been a very positive person, very upbeat, but lately Ive been having a stomach sensation like riding a roller-coaster. Its very brief, almost straight up from my belly button,and doesnt seem to be related to what Ive eaten or any new meds. Ive been on insulin for several years and my dosage was increased substantially a few weeks ago. Otherwise, everything else is about the same. Great wife, friends, no stress, ect. Any help would be very much appreciated ! TY so much !
