Wellbutrin XL

hi, ive posted here b4. i dont have a username, but i go by fatryan. im bipolar I and in the process of finding the right meds. after trying basically every med, ive landed on geodon to control my manic episodes. it seems to work. ive been doing really bad lately with the depression side of my disorder and recently started taking wellbutrin xl again. ive noticed though, that every time i eat anything, i get bad stomach pains. i remember i was like this b4 when i took wellbutrin. is this a side effect of the med? will it subside? TIA
