ambiens weird. it dosent make you the least bit tired... but if you take it while laying down with the intention on going to sleep, itll knock you out and before you know it youll wake up the next morning just like that. but if you stay awake, it does make you trip. sometimes if i have a really empty stomach or take more the one pill ill see shit. it puts my mind in a totally different reality, its pretty cool... but not something to do frequently. my doctor only perscribes me 10 pills a month for fear of addiction.
