3rd and 4th plateau doses would vary from person to person, depending on weight and experience....i'm sure i was on that border between 2 and 3 though...i was fucked up....i can't wait to try 600 mg....xanax makes the trip stop and you start to calm down...valium has the same effect...i would imagine alcohol would make it easier to come up on.....it is a little more dangerous tho...
