I am eating about 1.75g right now. I may drop it down to 1.5 though, to save a little on the grocery bill. 1.5 would bring me at 286.8 grams per day.
I use the bathroom twice per day since I have been eating 1.75g/lb, but think it has more to do with my overall calories versus protein, but when I drop it next week, I'll have to keep track of that.
