Health-wise felt amazing, there is a noticeable difference - especially when working out, it felt like a huge barrier disappeared, both in terms of diet and exercise ethic. Full weekend to enjoy with no hangover. Save a lot of fucking $$$. You begin to realise that you only see some people over a drink or that a lot of your personal/leisure time is just spent boozing and it's kind of eye-opening.
Pretty much this and I'm only 4 months deep. It's given me mad clarity, I've become so much more in tune with myself and feel emotionally stable and cognitively sharp. My decision making is better and you begin to realise how many poor choices were driven by the sauce, and I don't just mean those immediate ones while under the influence. The after-effects of alcohol/drugs are incessant and essentially never leave when you're on it every weekend.
Generally, I just feel way more energised and full of conviction. If you suffer from any sort of depression/anxiety/confidence issues too you'll be amazed at how quickly those feelings start to evaporate.
Physically, I feel much more trim, with better skin, hair, eyes etc. Internally I can sense that I'm functioning more efficiently too… 'new body who dis' kinda vibe. Also had some problems with my heart (pericarditis) the past year or so and that's pretty much gone.
I still go out no problem but I'm just more selective and it can be tough to see some of your associates through the harsh lens of sobriety. I'm only 26 but it just got the point where I looked ahead and wasn't looking to feebly roll into my 30's without a clue. Different for everyone of course and I guess a lot of people can enjoy alcohol without excess but if that isn't you then it's probably best to just knock it on the head. Smash your stag do and then give it a try.
For the single mandem looking to draw girls then trust me alcohol ain't helping you either. I've had a few amazing experiences since that I know I definitely woulda shanked if I'd been drinking.
