TMI WARNING: does anyone else have bowel problems once their medicine kicks in? I take the extended release and it seriously messes with my BMs. sorry for TMI but I really have been having this problem and it makes me late for work sometimes in the morning. I know you're supposed to eat food with your meds but even when I do, especially when I do, it makes the BMs worse. I've tried fiber rich foods and it doesn't work either.
