Basic dosing questions belong in Basic Drug Discussion. But alprazolam and xanax are the same thing. xanax= brand name of alprazolam. If you have no tolerance, you seriously are risking serious respiratory depression. I would avoid going to sleep if possible. I would seriously have someone come watch you, and if you become too far gone CALL 911 IMMEDIATELY.
The reckless mixing of three CNS depressants is dangerous and downright stupid, if you don't know what will happen.
Since these kind of self serving threads do not belong in OD, or anywhere really for that matter, I am going to close this. Refer to BDD and the search engine if you seriously do not know what each of these drugs do.
Watch your breathing, and have 911 on speed dial. Call a friend to watch you, as well. This was not smart, but for your sake I hope you end up alright.
