It once felt great, and now physically don't

I am to the point where my health is destructive because of my drinking needs. I used to be able to look forward to drinking knowing that I would feel great and happy that night. Now, it is nothing more than a crutch with physical problems.

First, I need to say that I am considered the norm when it comes to my height and weight. I am not overweight, but rather the proper equilibrium. I'm 5'9" and 160lbs. Though, I was more athletic in the first part of my 20's, I now have a little bit a beer gut. When I mean little, I mean, i can't see the abs I used to have with a layer of fat. My metabolism has always been high throughout my teen years going mostly through my 20's. In those days, I couldn't gain a fucking pound if I tried.

Now, I see my metabolism slowing down allowing me to have gained about 10lbs over the last two years. Apologies if that sounds minimal to anyone reading this. I have never been able to gain weight until now... how minimal it may seem to others, but a stark difference in regards to my entire lifespan.

What really has hit me because of my drinking has been my psychological mentality, as well as the physical health the days after drinking. I would wake up still tired from the previous night of drinking, sometimes with a slight hangover. This would put me in a shitty mood to begin with. On many days, I was an itchy trigger and in constant annoyance.

This would also cause me to have no motivation to do the things I told myself I would do the day before. "Should I finally get out and work on my car? Eh, fuck it. Its a little cold outside, so I'll do it tomorrow."

That is how things would pan out in my head. My level of procrastination has grown to a point where I no longer manage to function in the same way I used to back before my drinking problem.

How I feel the day after drinking:
Sadly to say, I have made a habit of drinking every night, which makes every following day the same. I sleep a decent amount of time only to wake up in the afternoon. I wake up tired, and have started going to the likes of caffeine to at least put me to sound mind along with getting rid of my slight headache.

Regardless of the ideas I figured I would get done during the day only turn out to me procrastinating as already said. I survive the 10 or so hours after waking up only to gain the lust to drink again after everyone else in the household has fallen asleep.

This is not the way I want to live, and I know this is slowly killing me.
