With the several days consumption I missed the first night sleep and I don't think much would have helped. The second night I got about 3 hours sleep and after that I was getting 6 hours sleep, but woke up at any but the slightest noise (GBL did the trick one night though).
The tolerance issue is quite useful in that it reduces the time that the drug affects the CNS as well as reducing the sensitivity. Got to admit though, that first night I never even thought about sleep, just sat quite happily doing 'housekeeping' on my PC and looking after my cat that was ill. The second night could have gone the same way, but I knew I needed some sleep so did try.
Of course that was with 10mg/day wheras desoxypipradrol was intended clinically for doses of 1-4mg, so that would be better fot getting to sleep
