bipolar disorde
"I switched from generic immediate release lamotrigine to lamictal XR about a week ago. In the last week I have had the unfortunate and horrible side effect of diarrhea. The worst I have ever experienced; it would start a few hours after taking my meds (at bedtime...) and last until about noon the following day. It took me about a week to realize it was related to the medication change. When I stopped taking the medication the diarrhea went away. I've seen tons of positive reviews about the XR, but it just wasn't for me. I gave it a 3 because it still stabilized my mood while I was on it."
