I'm having same dilemma, in doing 48 hour regime, it's still long enough time that in between you can get nervous. I am thinking of taking normal dosage of 0.5 mg of Xanax in the morning of each of the two days, before my 3 x 0.5 mg about 40 min before the SN time. For me it doesn't make me fall asleep, but might not be the case for you, but that's what I plan to do to relax myself about this
