I should be getting my NAC in the mail soon and I'll start taking it on October 1st. It's going to be a little tricky to gauge if I pull less simply cause there are a lot of times where I'm not aware that I'm even pulling. And there are just random days were you do just pull less (who knows why). So looking in the mirror will probably be the easiest way to tell if the NAC is working. So I'll be taking before and after (at the end of November) pictures. And on top of taking NAC, I really am going to try not to pull... cause honestly most of the time I don't try at all. Hopefully I'll have a full set of lashes, filled in brows, and no thinning spots in the near future!
