I did try the 150 mg extended release last night. I went to bed at 9 pm (I never go that early). I slept well and this morning just sort of feel like I'm floating along. not up or down. the only different affect is that my mouth feels sort of dry and thick. We will see how the day progresses but as of now I do feel a difference, a sort of slowing down which feels okay. I don't feel totally sedated or anything like I did with the fast acting yesterday.
