I have been on Celexa for 13 years (20 mg per day). I took 10 mg a day for 2 months and then 10 mg every other day for 2 weeks. The last 2 weeks I have stopped totally. I have unusual bowel movements twice a day but am left with a feeling where I can't totally empty my stomach. My stomach is very bloated. Is this a side effect of stopping the medication?
