The GI side effects for me are bad. Each time I titrated up, it lasted for about a month (stomach cramping, nausea, diarrhea, loss of appetite). Instead of separating my dose between AM & PM, I moved my full dose to PM, right before bed, so most of the nausea happens while I'm sleeping and doesn't affect me.

Honestly though, I hate it. I'm working with my pdoc to switch from Lithium to Lamictal because of the side effects & lack of results. I've been on a therapeutic dose for 2 1/2 months and I'm definitely not where I want to be. I would say if Lithium helps you get where you want to be, it's worth trying to tough through the side effects to see if your body adapts over time. Finding something that really works is the ultimate goal, right? Just talk with your pdoc about your levels and make sure all is on the up-&-up.
