Some agreement here with the above responses. Feeling well does not mean you are cured; it means only that you are stable. One needs to continue to take medication and treatment to maintain this. Yes, there can be unwanted side effects but if it means remaining emotionally healthy we must be prepared then to accept them.
Personally I have a great deal of difficulty with feeling 'dumbed down' by my meds. I resent the weight gain. But I realise my life would actually be worse if I stop taking my medication to avoid these things.
Please talk to your doctor and follow their advice.
