For me it has, and I know from back in the day when dsade was a regular poster and other RPN guys posted a lot, at the time they were recommending online to do 3 x 3. I've since seen them change to 2 x 3 + 1 pre bed. They say it works better but I didn't find it to be as helpful for me as the 3 x 3.
I'm trying to get a sense if the 3 pills at a time is now being viewed as too much at once? Otherwise, I'm going to stick w/ 3 x 3 and maybe +1 pre bed.
