I'm just throwing this out to everyone because ever since I started lifting again last October I have had unpredictable, sometimes explosive and always soft bowel movements. On top of this I sometimes get a "sour stomach". The lifting coincides with an immediate change in my diet which includes a PWO shake (Whey, water/skim milk, banana and berries, splash of juice) and possibly one shake with breakfast when I first get up. I can't say for sure that I am not Lactose intollerant, but when I make the shakes with no milk, I still have this problem (although I do still add a bit of yogurt sometimes). I will be seeing a doctor this week as this has gone on far too long. My question is this...Is there anyone else out there who just can't digest powdered protein forms? (if that is indeed what my problem is) Is this common? And what do people do for Post WO food instead of shakes? Any info would be great as I am actually getting a bit scared...I am only 27 and I'm praying there isn't something seriously wrong here...
