Well, obviously the idea is to only sleep-deprive yourself right AFTER (and only IF) the bad has already happened. So instead of going to sleep after being completely sober again after the trip, you would take some uppers instead and keep yourself awake for as long as possible
That would most certainly cause a bad trip at night. As taking uppers to stay awake for long will also increase anxiety, which will not be helped by the residual hallucinations from the earlier hallucinogenic.
