They're Nuts! follows the activities of the Nutville Internal Medicine clinic and their patients. This comic primarily focuses on diabetes and health care humor. It also has a nice twist of randomness to keep it interesting.
Bariatric and lap band surgeries are very complicated in more ways than one. I'm not saying they are a bad thing necessarily, I'm just saying they are not for everyone. In my personal opinion, it should really be reserved as the last effort to potentially save a life, and not viewed as an easy fix or a cure. Once the surgery is over, a whole new set of problems often arise.
Have you ever considered using a vector program like Inkscape? It would allow you to keep the simplicity of your character designs, and still pull off a more polished look. For instance, this was done with Inkscape.

The best way to appreciate weight-loss is to work really hard for it. Then you'll be more careful about what you eat because you remember just how much it sucked to lose the weight.
