There's nothing pathetic about struggling on day four. The alcoholic part of your mind is hurting and knows that first drink is an easy, temporary fix. But that same alcoholic part of your mind is conveniently glamorizing that first drink while ignoring all the bad that comes with drink three and five and six and eight, etc.
It does get easier with time. I'm living proof of this. I was a daily hard drinker for fourteen years. Have sixty days sober now and haven't had a craving of any kind for almost two months. My life is improving and my mind is getting clearer in little ways each and every day.
