Hey Sweet...I give you so much credit because you keep "trying" to stop....its so difficult especially when you feel horrible....
I read your Mom has cancer...all the more reason to work really hard on stopping because she needs YOU around for SUPPORT...If you are feeling unwell...and miserable...you can't be much of a support.
Also, drinking alcohol makes us all prone to getting cancer more than the average person and because it is in your family history...it would be really good if you could stop now.
As far as eating..the first 6 days of my sobriety all I could eat was Watermelon...the most important thing for us to do in early sobriety is to get HYDRATED....with Gatorade or Pedilyte (Pedilyte is expensive but a couple bottles made me feel a ton better)....
Your humble enough to come on and post when you drink and to talk about it...I hope you find it inside to be humble enough to admit that you have had enough alcohol...time to try something new.
