At 5mg, the usual and expected side effects of nausea and diarrhea, which were worse if eating carbs. Those side effects were not that bad, and I lost 6 pounds during the month I was on the medication.
I then was increased to 10 mg. That was when I started experiencing problems. Incapacitating abdominal pain and profuse diarrhea which would last for about 2-3 hours, and hit me in the middle of the night every night I was on the medication. I also had *very* intense carb cravings and a compulsion to eat and just couldn't stop eating. My doctor took me off it after a week of this, and said that he had heard of the increased appetite and carb craving before. In one week, I gained back the 6 pounds I had lost the month before.
