Waist Decreasing on More Protein?

My only issue with the extra protein is the gas and the bad breath issue. I’m actually thinking of cutting back on my protein, because of this. I’m @ 140 g per day (weigh 137 lbs). I’m going to cut back to 100 g per day and see if those symptoms go away.

I hear some people on here doing 2g/lb…how can anyone do that much! Wouldn’t that give you horrible gas and bad breath!? I would only consider that much if I was a professional bodybuilder and I’m far from that.
