Gabapentin really helps me. I only take it at night and PRN although I have 2 doses at night; one with my other meds at 8:30 and another 200 mg at 11 pm because I was getting anxious and not able to sleep. Right now this is working very well for me. I don't take it in the day because I'm not good at remembering meds aside from night or early morning (and now that 11 pm dose). Combined with clozapine I really am better off with anxiety than I ever knew was possible. I hope you get the same result.
