5-6 now but I am not drinking any coffee either. About the same as I was getting before drinking a ton of coffee. The big difference I am seeing is that before I would still be sound asleep when alarm went off, hit it a few times, and then be rushed getting ready. Now I am usually waking up before the alarm every day and can just pop out of bed. Your mileage may vary of course. I can't sustain less than 4 hours sleep for any length of time. 2-3 hours is crazy!
