Yes, the first few days are scary. Physically and emotionally. Make sure you go and see your doctor Plenny if you are really concerned about your health. I'm sorry you're feeling like this. I know you already know that these feelings won't last but that probably isn't much help to you right now. Just drink lots of water, eat when you're hungry and try to rest when you can.
I feel so fed up with being an addict today. Most days I feel ok about it. I accept that there's worse things in life than being alcoholic and all I have to do to be free of symptoms is not drink. Simple. Today it doesn't feel simple. Today it feels overwhelming. Today I feel like I want to scream, "why is it so hard??"
It's not even that I want to drink. I just want to be free of all the thought patterns that turned me to alcohol in the first place. But I guess as Steely would say, "there's no way through it but through it".
Let's just stay sober and keep going Plenny. I'm with you and sending you lots of love xxxx
