Lithium gave me constant diarrhea! I mean, I had to run out of class in the middle of an exam kind of bad lol. I also got toxicity from it. Abilify gave me restless leg and heart problems. Some people can get stable from APs alone I guess but I always need a stabilizer. My stabilizer now is gabapentin and I don't even need my benzo anymore because gaba works on the same receptors. That along with geodon is working great for me so far. As far as a med change goes, if my appointment is like in the next few days I just stop taking the med that's causing me problems. That is if I know it's going to be discontinued.
