There is nothing strange about your addiction. I thought so too, im different. That is a lot like the bulk of my 27 years or so of drinking.
Many in recovery were all out, all day drinkers that needed a serious detox. Then again, many more are just like you and me. Stick around and you will see its about what we have in common. An almost allergic reaction to alcohol that makes us lose control combined with an obsession to drink it.
If you ever attend an AA meeting you will find many drinkers just like us. My issues are likely a bit different but I definitely relate to the pattern. You will find many have anxiety and depression. Symptoms of restless, irritable, and discontent sometimes when we don't have alcohol.
The big book of AA is available for free from many google search results. I think you may find the reading pretty interesting even if you don't ever wish to attend a meeting. The information about our condition is far ahead of its time.
