Hi Nighthawk,
Stay with it and you will feel better. I do hear alot of illnesses in the beginning and when you feel sick you'll almost do anything to feel better. I am over 18 months sober and I still think of having a drink when I get sick.
You may also want to look into something called PAWS. I'm not sure I experienced it but many have and you can find alot of information on it. I think it can happen for around 6 months or longer. 23 days is great and just know that it will go away and you will feel better. It really sucks when you think you are doing everything right and you still feel sick. Good luck you are doing great and always seek out what is bothering you. This site is great for that.
