opi8, Id cut it down to something more moderate. Just because you dont suffer physical WDs doesnt mean you arent consuming too much, you may even have to watch yourself closer because your body doesnt throw up warning signs (DTs) like the rest of us.
I love booze almost as much as I love life, I am the progeny of generations of alcoholics, and I associate with mostly alcoholics on my spare time... I dont throw a "cut it down to moderate levels" blurb in lightly. But just about everyone I know who regularly drank even "just a little too much" hit a health snag well before their time (15 drinks is a bit much my friend

)
You know full well how poisonous the ethanol we saturate our organs is. I fucked up my body with booze by 26. Im awaiting blood work on what I think is a kidney disaster but MD thinks is a liver problem (no jaundice though). Constant tightness/awareness of my lower left and right back where the kidneys hang out IIRC, severity increases with booze or pill consumption. Also Ive had gastritis and a damaged esophogeal valve which gives me ruthless heartburn that even old people dont experience since my early 20s. Even my people like you who only drank less abrasive beer get caught up in the long run when we start talking "a little too much," that much ethanol inevitably takes its toll on human tissue. Its not if its when, and what better time than now?
Sorry for the length didnt wanna double post this next bit.
Re: a couple posts comparing beer vs liquor in dependence. I experienced more unpleasant withdrawals when Ive used rotgut liquor, than the times I achieved physical dependence (the shakes) on beer alone. It would seem to make sense that 15 units of ethanol a day is 15 units of ethanol a day, no matter what the method of ingestion is, but liquor WDs are somewhat harder on the body in my personal experience. Could your body process them differently due to the large strength disparity?
Another reason liquor is more conducive to WDs is because you can get waaay more ethanol into your system much much quicker. During my heavier use I would take a coffee mug of liquor (4-5 shots) upon waking up and my addiction compulsed me to have at least a doubler every ~45 mins, Id be functioning drunk by noon. Due to beers low ABV, it would be physically impossible to achieve my median BAC in the daytime. My physical dependence would absolutely decline, Id be sober most of the morning. All the time it takes to down individual beers, plus time for your body to process all of them . With liquor, Id have 5 beers worth of ethanol absorbing into my system before I even rub the sleep out of my eyes. Sobriety was virtually non existant with liquor, but sobriety is unavoidable for a tolerant drunk who has to drink several 12 oz beverages then wait for the body to process them.
Severe alcoholics usually need hundreds of fluid ounces of beer all day everyday to maintain, which is physically unpleasant to consume and deforms the body, which definitely isnt for most people. By comparison, liquorholics consume a mere 1-3 pints of spirits a day, and 3 is being generous. Its much easier to imbibe higher amounts of alcohol in shorter amounts of time with liquor, while avoiding the duration of a sober onset and unpleasant physical effects brought on by a gut full of beer all day. You urinate exponentially less, avoid a million calories of constant fluid intake with liquor, spend much less money, and the ABV means you can carry effective doses around most anywhere in your hip pocket (flask). These things make liquor a much more practical choice for severe alcoholics and therefore easier to fall victim to.
Personally waiting around sober for 2-3 hours for a bunch of pisswatery beer to register was excruciating at my level of alcoholism, beer was literally useless with my tolerance. My morning tremors would render basic activities like paperwork, email correspondence, meal preparation, etc, difficult or impossible if untreated. Sitting around a couple hours waiting for beer to meet my BAC requirement would be absurd. This degree of ethanol dependence can and does occur with beer drinkers, but you almost have to jump a few hurdles to get there. Beer drinkers will be A) facing sobriety at length in the morning waiting for a weak alcohol solution to meet your neccesary BAC, B) require a fondness/ability to pounding large volumes of pissy liquid daily and C) must be apathetic to to the physical effects of drinking barrels and barrels of beer, and D) be willing to forego the convenience of concealed maintenance doses.
Sorry its a long post but I havent been able to sleep the past couple nights, and this is actually supposed to be 2 posts.
Edit: I rounded a lot of my figures for simplicity sake. For example, I dont think it would take a full 100 ounces of beer to supress DTs nor do I swear by 2-3 hours to process that amount. My experience with beer withdrawals is comparatively limited but Ive shaken em twice and liquor a handful of times more than that. I also understand my level of alcoholism was a bit deeper than what is required to form basic DTs, Im simply relating personal results to illustrate differences I experienced between beer and liquor. I guess this is more of a disclaimer for the pedantic drugophiles around who get all nitpicky if you arent spot on with uptake/excretion info, pretty sure most could get the gist.
