I am really new to this whole treatment thing. I'm up to 100mg of Zoloft and 150 mg of Lithium and I'm taking Lunesta occasionally to sleep. It's been about 5 weeks. I don't really feel any different but my hands are really shaky all the time. I didn't even notice until one of my friends pointed it out to me. Since then it's gotten worse and more people have noticed. My legs are shaky too sometimes. Today it was really bad and my arm muscles, like my biceps, were spasming a lot. Is this a common side effect of zoloft? I mean I guess it could be a manifestation of anxiety but it feels different than my normal tics, like it feels even more involuntary (if that's really even possible). I really don't like it. I mean I guess shaking a little is better than feeling sucidal but I still feel that way too sometimes.
