I was looking through some old posts and found this one! I started the P&B shakes approx 3 weeks ago. I had tried them several months ago, but they made me too constipated. Anway, when I moved up to two shakes per day I had gas like you wouldn't believe! Luckily most of mine occurred in the evening with no one around : ))
Anyway, I moved back down to one shake per day. Because I only have one bm per day I assumed this was the problem. I thought maybe the fecal matter was in there too long without coming out. How many bowel movements do you have a day? (Imagine asking someone this question in a "polite" conversation?!)
By the way, I am taking an herb entitled "cat's claw" which is an intestinal cleaner. Also...each time I do an apple cider vinegar enema (2x per week) I release mp!
