This January I was diagnosed with Gastroparesis. In the Fall, stomach pain effected my sleep and I got overtired. This led to me getting scared and confused about irrational things. I was taken to a hospital and put on a psychotropic drug called Abilify (20mg). I was on the drug for 4 months and then tapered off of it under doctors direction. I've been off of it now for almost two months.

Unfortunately I'm still having symptoms of muscle ridgidity and lightheadedness, which I first remember having while on the drug. I sometimes feel like I'm about to faint when going from sitting to standing. There's tension in my left leg that causes me to wiggle the toes on my left foot. My muscles quiver within like at the end of a set of lifting weights or doing pushups. I've been to a neurologist who has referred me to a movement disorders specialist. I'm not diabetic. Hepatitis and Wison's are ruled out.

Is all of this still side effects? If not, what could it be?
Thank you very much.
