Hey Stronger-

I'm not sure if you are taking the tablets or capsules of lithium, but it comes in both formulations. In theory, the capsules are easier on the stomach than the tablets because they are coated, etc. however I actually found the opposite to be true [which makes no sense even to me].

My suggestion would be to ask your doctor and pharmacist about this- it may be worth it to at least try the other formulation for a few days.
