I had a lot of trouble throwing up all my meds as soon as I tried to swallow lamictal or lithium carbonate capsules. My pdoc switched me to the "baby" version of lamictal so I took 7 little chewable pills instead of the ones that made me throw up. I took them in baby food so that I could vary the taste that I was associating with the pills and that helped too (when I took it with pudding seeing the pudding made me sick or whatever). I also changed to a different form of lithium and the vomiting stopped for the most part.
