The worst is when we try not to think of things it is impossible not to. You have to find positive reinforcement for not drinking. Like finding you have spent time doing things and it hasn't entered you head. Or waking refreshed and clear headed in the morning, enjoy and rejoice in that feeling; recall it through the day and look forward to feeling the same again tomorrow morning. It really is a mind game and you can control it. Focus on the positive changes to your appearance. One month in is very early and what you feel now will be a dim memory in the near future.
