I have actually struggled with this for some time and tried these to name a few:
tylenol PM
unisom
benadryl
Rx
sonata
lunesta
ambien
In the last couple months I have been using USP Labs REM R3G and loving it for both my gf and myself. Within 10 minutes of taking it, I cannot even keep my eyes open. I am laying there having a conversation with my gf, and boom, I am listening but just don't have the energy to respond. That is usually it, as long as the conversation was not on something of importance, b/c if that is the case, I will get yelled at and elbowed for passing out on her, lol...btw, there is definitly something going on with this product, as every night since I started, I wake up in a pool of sweat, to the point where I must lay down towels....
