Gas and bloating from smoking ecigs

I have a iliostomy and I quit smoking after 30 yrs. I started smoking ecigs and I use the Itaste mvp with a Kanger Pro Tank 3. I have been having a lot of problems with gas and bloating and I'm sure that it is from all of the air that I am sucking in from the Protank 3. Does anybody have any suggestions on what I may try to help me from getting so much air intake. Thank you and God Bless :)
