I have felt like this also, especially when I had all the head hunger. I was "mourning food" but it gets better. Just hang in there and keep your eye on the prize.
I had mine on March 6th. I got rid of most of the gas/air pains before I left the hospital by walking a lot. But I do feel the pain more now, mostly on my left side. I think it is because I was more medicated in the hospital. Now that I am out I only use the liquid Hydrocodone before bed,and extra strength Tylenol during the day so I am guessing this is why I am feeling the pain more But I am sure things will be better in a few days. But walking does help alleviate the gas.
