Gabapentin
"Gabapentin is the most liberating medicine I have ever used. I have tried Effexor, Prozac, Paxil, Zoloft, Lamictal, Lithium, Phenibut, Kava, Theanine, -anything with implications of anxiolytic properties. Finding the right dosage can be a little tricky, but when that is tuned, this medication seems superior to any anxiety medication available.  Side effects of too much- dizziness, fatigue.  "
