Severe Bloat and Belching

My wife and I started the V-Diet today. I have had no problems so far but I drink protein drinks on a regular basis. My wife however has had severe bloating and belching all day long, so much in fact she can barely get down the next shake. I tried to space them out a little farther apart but the bloated feeling remains. Would taking Simethicone(anti-gas) supplement as needed hurt the diet plan?
