All the current research seems to indicate the time of infusion (4 hours) is more important than the dosage. It's all very individualized but the goal is to do the highest tolerated dose, but you have to work up to it. The standard protocol is start at 60, try to work up to 200 by the end of the 10 day treatment, usually 60,80,100,125,150, 2 days off 125, 150, 175, 200, 200 or something like that. Versed given concurrently to control the dreams and stuff and a 10 minute pause in the middle of the infusion. All the reputable dr's and clinics are doing it this way now. I'd be very leery of other things, especially shortened infusion times.
