Akathisia is by far the worst. I think it should be classified as torture. I have akathisia right now but I just got my klonopin dose doubled today so hopefully that will help.
I stopped the worst of the akathisia by taking vitamin B6, NAC, and Benadryl together, the akathisia improved overnight.
I can understand why people with severe akathisia sometimes off themselves.

The brain zaps were like a walk in the park comparatively.
