I hate to say this Ill, but the first thing you need to do is stop drinking. I am not sure why you are consuming a lot of alcohol, but it is very bad for you body, yeast and for your mood.
I am not sure what you mean by the link between being autistic and carb-cravings. We all have carb cravings. If you stay on the diet proposed on this site, the cravings get better.
Your tongue does not look that bad to me.
I am not sure what else I can suggest to help you.
