I have always had a few weird what I now call ticks. I used to blow on my hands like I was freezing no matter the temp. People annoyed the living hell out of me asking about this. So I guess i subcontiously switched to a new one. I have been swallowing air and burping as quietly as possible for like 3 years. I can't stop. The more people give me looks, the more nervous I get and the more it happens. Is there anything I can do to stop this? I am really sick of it and it is causing me heartburn, as well.
