insomnia
"I was prescribed Gabapentin for anxiety and insomnia. I was diagnosed with severe obstructive sleep apnea and had a tough time getting used to my CPAP and didn't sleep for several nights in a row. The first night I took the Gabapentin I slept! And I've slept every night since then. I take 800 mgs during the day and 800 mgs at night for 1600 total. I sleep between 7 and 9 hours every night now. My neurologist also told me that Gabapentin increases slow wave sleep. Before my CPAP (and the Gabapentin) I was getting no N3 slow wave sleep at all. So this drug is amazing for sleep, for me at least."
