Magnesium didnt do much of anything, niether did phenibut. Maybe im taking too little, but I started off with 500mg and gradually increased my dosage by 500mg. A couple of weeks ago I took 2 grams but didnt feel much. I did sleep about 12 hours that night. The next day I felt a little cloudy headed but nothing too dramatic. Ive been trying to adjust my sleeping schedule so im kinda reluctant on trying for 2.5 grams. I just ordered some L-theanine and picamilon so ill see how that goes.
