(Ive drunk everyday since wednesday, pretty heavily and im going out AGAIN tonight! NOT good, my liver will be pickled!)
I wont be able to go out as often if i go straight to ATC.
Mate, going by that quote I would go to Uni first, it'll suit the lifestyle you currently want perfectly (not a criticism, we all, well most of us, have been there!). When you've got a degree and got the partying and boozing out of your system you will be ready to move on into a career. Bit more mature, bit better equipped for the studying that you'll face etc etc.
As a side note, I would defo recommend that you stick with NATS. I went down to Swanick a few months back to do a TRUCE day and I have to say had a thoroughly enjoyable day, learnt a lot, increased my admiration for the guys and girls that do it for a job ten fold from already stratisferic levels and personally would give up my seat in the flightdeck in a heartbeat to go to Air Traffic. An infinately better working environment and thoroughly more enjoyable!
