I take the instant release, 30mg three times a day. I usually feel it kick in after 20-30 minutes and lasts about 4-6 hours.

I find the effects of the quick release option within about 40 mins but last nowhere near the suggested 6 to 8 hrs - for me about 3 to 4 hours. I take 5mg (half a tablet) 3 times a day - morning, lunch time and late afternoon.
