Your are not a failure. It is probably really bad gas. I had the same issue and it was coming out of both ends at the same time. Try to walk as much as you can, that is what I did. The beginning is always hard. Do not expect to be able to drink much, small sips all day. I only was able to handle chewable vitamins for about 3 months. You should start feeling better in a couple of weeks. That was my major issue, gas and not being able to go to the bathroom. Once you are able to handle more, your bowels will come around . I had my surgery 11.9.16 was a size 22 I am now a size 8. I take miralax a scoop everyday in my morning protein shake. Just think of what you will look like when a couple of months. Try to keep you chin up, this shall pass. I look at myself in the mirror and do not even recognize myself.
