"i take effexor for anxiety which has greatly increased my insomnia. without something for sleep, i&#039;ll wake up anywhere from 20-30 times a night. i fall asleep easily but wake up repeatedly. i&#039;ve tried many things over the years to try and help improve my sleep; 5htp, same, melatonin, phenibut, klonopin, trazadone, seroquel, etc. the gabapentin is a life saver. i take it at the same time every night and sleep like a baby. there are no side effects that i can tell and zero grogginess in the morning. i&#039;m amazed that i wake up refreshed and ready for the day. i haven&#039;t slept this well since i was a child. i highly recommend being open to trying this if you&#039;re suffering like i was."
