I get nasty upset stomach sometimes after drinking a serving of Met-Rx. I use about one cup of milk-sometimes two and top it off with either water, juice or diet soda. I usually get realy bad gas from it naturally, that's no shock for any bodybuilder who takes ANY whey based MRP. But I was whondering if it may have something to do with adding the milk or if it's just the drink itself? I'm not lactose intolerant so that's out. Anybody deal with this?
