Hot Flashes
"Continuous hot flashes at least one an hour during the day and at least 5 to 6 during the night, waking me up, over the last year. Was required to stop Estrogen patch after breast cancer scare one year ago, and Cold Turkey on the hormones sent hot flashes, sleeplessness and irritability off the charts. 
Gabapentin was prescribed and was an immediate success at stopping the night sweats and hot flashes.  I took it at night and it worked wonders...I finally switched to a PPO insurance plan so I could choose my own OBGYN.  (Was previously on a HMO and no doctors would provide any help or relief from hormone issues.)
Gabapentin stopped  hot flashes and insomnia within 2 days."
