Be careful with Zopliclone (ie zimmers) they can give amnesia and they are the worst tasting pills i have ever had, i'd say take 2-3 your first time, just to see how you feel then maybe up the dosage. Tolerance builds fast with these, so don't take them too much. I'm on 7.5mg tabs and i take 15mg a night. I usually wrap them in a cigarette paper and bomb them, because they are disgusting if you don't swallow them straight away
