I would turn to more fruits and veges before trying something that is man made. I would keep up the diet you have, just go to web MD and look up colon cleanse or something to that effect. Or google "veges with fiber" and see what it brings to you. I'm sure that nature will help clean you of the waist you have piled up in there.
I experienced (am still) the same thing. I can honestly stink the dog out too. That's bad!!!! So I feel your pain!! Just make sure to stay away from soda and coffee, milk products and add more fiber to your diet. You can also expiriment with Acai Berries. I have ordered mine and will let you know how they work. You'll just need to send me your email. Mine at home is ____@____.com
The other thing is to exercise a little more and not too much or you'll get exhausted and your milk supply will go down, but maybe 30 minutes every other day until you can rebuild your stamina back up. That will help joggle that extra weight around and may cause more gas, but it should help get the bubbles out along with the added fiber in your diet from veges and fruit to get you back to pleasant smelling.
Best of luck and just know, there are others out there who are suffering the same thing right along with you. If you want to know how that Acai Berry stuff worked, send me your email and I'll let you know pronto.
