I got put on it almost 2 years ago, and worked up to 1500mg a day (600mg in the morning, 900mg in the evening). I’ve had chronic, almost daily diarrhea since then. For awhile I couldn’t really pinpoint what was happening and attributed it to bad diet. My diet is inconsistent (sometimes will binge and eat a lot of processed foods, other times I eat a lot of veggies. I’ve cut down on sugar intake these past few months). but even when I have periods of time where I’m eating somewhat normally, I still have diarrhea. I’m considering going to a GI doc to do testing but I have no symptoms of celiac or other GI diseases. I plan on mentioning it to my psych but my next appointment is in a month. Any info on this? I drink caffeinated tea 2-4 times a week which I know should be avoided while taking lithium.
