I have experience with Lithium, which I have taken for about a year now and no longer notice any side effects. During the first months it regularly caused me an upset stomach and nausea, but this is a situation now overcome.
For about two months I took Abilify, but this drug caused me urinary retention and I had to stop taking it. Instead of Abilify, I am currently taking Risperidone, I am adapted to it and currently without any side effects. During the first months it caused me dry mouth, great thirst, drowsiness and clogged sinuses.
