"i was prescribed gaba by my doctor for insomnia. i find it does help to keep me asleep once i get there. i agree it doesn&#039;t put me right to sleep however i find that it does allow me to relax my brain and body so they&#039;re not going 100 miles an hour which then allows me to fall asleep. i was told to only take it if i had 7 or 8 hours dedicated for sleep so what i found was this. when i take it and am allowed to sleep a full 8 hours before getting up i feel great in the morning. if i take it and have to get up in 6 hours i&#039;m disoriented in the morning and vision is blurry. so with that being said and knowing it takes a couple hours to fall asleep after taking this i&#039;ve learned my time table of when i take it where i get the best results."
