The meds have helped me no ends. It was only when i got up to therapeutic dose did they dissipate. Also , smoking , causes a rise in my symptoms. So maybe you could try an ecig for 2 weeks and see do you see an improvement. Tactile symptoms have long being associated with toxicity in non psychotics.

A combination of an antipsychotic with an antidepressant or anticonvulsat maybe useful. But you would probably trade with an increase of side effects or potential interactions. Depends how bad these symptoms are and if it is really worth it.

Try the ecig thing , if you are already a smoker , that is

There maybe also be a vitamin/natural option. rhodiola is something i came across lately...
