Zolpidem
"I suffer from serious anxiety which had been making it really hard for me to fall asleep, taking 2-4 hours to fall asleep and then when finally sleeping I'd always be waking up 4 times in the night and after two months of this, I was completely exhausted and went to talk to my doctor who prescribed me zolpidem. This medicine knocks you out right away but be careful - go straight to bed after taking it, because it kicks in fast and strong and the effect it has is kind of like being completely wasted and you'll end up doing silly things. If you go straight to bed, you get a good, deep 6-7 hours sleep, which feels amazing! It's so strong that my brother tried to wake me up once when I fell asleep on the couch and he couldn't! That NEVER happens!"
