for about the last year I have taken my immediate release 25/100 one and a half every 2 hours. This way i stay pretty much on and dont have dyskinesia. The only problem is the discipline to take the pill when my timer goes off, it's easy to go another 20 -30 mins. If I fall asleep and take a nap I usually miss a dose but I think that because I have a dose always in my system it recovers much easier. I also have to remember that more (2 tablets) does not get on board any faster, it just puts me over the edge towards dyskinesia. Seems to work for me.
