Thanks! Yes, it is expensive and it takes effort to keep up with spacing out the doses.

I had stopped GSH for almost a year and when I started up again, I could not pass 1500mg per day without having some issues. So, I've been at 1500mg for 10 months now. Previously I was on 3500mg per day (I'm about 120 lbs). Somehow, this lower dose has been just as effective for maintaining. I'm not sure why....
