I Tic Tac I'm on a thousand mg of lithium and 112.5 mg of Effexor. I believe it's the Effexor. When I was on 75 mg of Effexor and 600 mg lithium I did not have hand tremors but as soon as I increase the Effexor I had them. I'm on 20 milligrams of propanol and it does help I might try to increase it to more. I really don't like this drug Effexor but it's helping to quell about 70 to 80% of my anxiety. I want to change to an SSRI like I'm used to but right now I'm dealing with a storm and may not be a good time
