Toward the end, I was drinking all day long. I'd wake up in the morning shaking and the only thing that helped was a couple of shots of whiskey I'd take before I even got out of bed. Once those would kick in, I'd be more steady but well on my way to getting drunk. I'd do a shot here and a shot there all day long and by the time the evening rolled around, it was "game on." I'd drink until I'd black out, then I'd pass out, wake up in the morning, rinse and repeat. Awful way to live, for sure.
If you think rehab is the best option for you, I'd say go for it. At the very least, perhaps a medical detox to get the alcohol safely out of your system, and then a solid program of recovery.
