You can't drink alcohol at all. And you have to figure out how to remove the stress from your life. If you are too stressed out it will hamper your healing by 90%.
Just do what I said find a good naturalpath doc they will support you thought out your treatments. I have the same systoms as you and it is a fungus infection in my large intestines. They will tell you what's going one but find a naturopath will a good rating online there are some shitty ones out there.
YOU HAVE TO DO THE VITAMIN C IV. message me if you have more questions. Also if you are having problems with your mouth you have to heal that too at the same time.
