Starting ever 3-4 months, then every 1 to 6 weeks with no known trigger I get a burning skin sensation that comes on suddenly and within 10 minutes or so I feel blow torch heat staring with neck and face then limbs and trunk that actually looks exactly like a sunburn, but feels about 10x worse and no peel afterwards. And my face muscles weaken, face droops, and I look 10 years older at it's peak. These "attacks" usually only last 30 to 45 minutes and driving with AC on full blast or taking a cold shower is the only relief during. All I know for sure is this never happened in my 44 years until prescribed gabapentin.(Nuerontin). I have GAD and my doctor suggested a 400 mg pill along with at Xanax 4x a day. I have tapered down to 1 gabapentin in the mornining and intend to quit in 10 days. Bad news is I've been at the low dose for the last 6 months out of the 18 months on it and the attacks haven't changed as hoped, in fact I'm writing because I just had one last Thursday and again today (Monday, only 4 days later)... a new record for shortest span between attacks. Could recognize no benefit or difference with regards to it's effectiveness treating my Generalized Anxiety Disorder. The Xanax as needed appears to be all I need alone. Only exception being that early on if I took my 100 mg Xanax w/out a gabapentin you could get drowsy while driving.... I break them in 1/2 doses or drink coffee, does the trick. I'm on only these two drugs and don't see the same side affects posted about Xanax so I deduced it's the gabapentin and am stopping it. Yes I too noticed occasional blurred vision, confusion, and munchies, reduced libido, more difficult or no orgasm as well on gabapentin. Too bad.
