Aerophagia

For about 4 years now i have what i believe to be aerophagia. it is controlling my life and making me miserable. some articles say it's mainly behavioral but i have a hard time believing that because i will try and follow the suggestions and nothing helps. I can wake up in the morning, take a drink of water, and it will start...the constant, painful internal burps. they hurt so bad. it's gotten to where after almost every meal or intake of food i have to go stand over a toilet bowl and act as if i'm going to vomit just to get the air to come out in big consistencies. i don't know how to actually "burp" on my own, i never could do that. this is starting to affect my throat from straining. what's also wierd is that when i'm lying down if i lay on my right side it doesn't do it but as soon as i turn on my left side the internal burps will start constantly. i'm at a loss. i've been to dr's, tried all the different pills, and charcoal but nothing works PLEASE HELP. i'm miserable!!!
