It's been a couple days since I took the "Prescript Assist" trial pill and I can still feel the effects of it very strongly. I'm really considering giving it a trial run for a couple months now. The blue cheese I had to take for three months before it felt too strong; the 'ultimate 10' probiotic took a month to get me to that point. The fact that I felt that way after just one pill and still feel it is pretty significant.
