loose stools, about 4 to 5 times a day and nausea. I have been on it for 4 days now. I previously was on Zoloft about 7 months ago and had taken off and on for 5 years. When I initially started taking it 6 years ago, I had experienced weight loss and nausea (which probably contributed to the weight loss). I hate the loose stools, it creeps up on me with almost no warning. It's embarrassing!
