Other than GHB does anyone know of a substance that will increase deep sleep? Good deep sleep and rest is the last thing I need to complete my fitness goals. I have everything else in place but sleep is a serious problem. When I am in full out combat mode of training my sleep quality really begins to suck. Maybe this is an older guys problem (I'm 39). Someone please help my cranky sleep deprived ass!!!!! I'm not calorie restricted,cafienated,nicotined,stressed out,or into any stimulants. :sniper:
