if I have had a serious reaction to diazepam ( depression paranoia delusional ) bassically diazepam did the opposite of what it was intended for will gabapentin cause the same reaction ?? I can not take xanax or any drugs in that category due to the adverse reactions i have had should i worry that gabapentin might do the same thing?? I have been given gabapentin for nerve pain for my neck I recently had my c5 c6 and c7 fused together and was prescribed this for the nerve pain .. but after the reaction I had from the diazepam i was given for vertigo I"m leary of any drugs that have the possible side effects this one has ..
