Angryfeet and Newbie wow, that's some sober days racked up there, well bloody done! 
Newbie I'm not sure how to advise re the stag do, as if it's anything like the majority of celebrations of that type I'm fairly certain bucket loads of booze are going to be involved - for me at this stage of my journey I'd probably have to stay away, but that's a bit of a cop out answer, sorry!
I'm nodding along to so much of the above! nochips don't beat yourself up any more today, sounds like you've learned a lot from your blip and it must be really hard if you can't explain to those around you why even just one glass isn't a good idea. Keep on keeping on, you're doing so well.
Tabard I also had a pretty wild time in my youth; it's actually really embarrassing to say this but I made a better recreational druggie than I did a drunk 
in that I never 'lost control' as such, could always remember what I'd done/said (even if some of it was pretty random rubbish) and I never found myself in a strange place/bed/trouble the next morning etc. Only partied at weekends, mostly recovered by Monday morning...irony is I thought I was being grown up and sensible for sticking with alcohol and viewing drugs as an appalling activity once my DCs arrived...perfectly legal, acceptable, everyone else is doing it...so much more cleaner than recreational drugs...yet the truth is, they're both as bad as each other, in different ways granted, but both still guaranteed to fast-track me to a miserable existence. Yet alcohol felt OK to be getting stuck into on a regular basis.
I'm still clinging on to my e-cig (for now, one thing at a time! 
) and neck large amounts of coffee on a daily basis, so I think there'll always be parts of my addictive nature that I'll never quite see the back of!
