How were your sober experiences?
I actually had to drop out of the festival for a personal reason which was disappointing, although it did mean I could attend Wide Awake on the Friday so wasn't a complete loss.
So having attended a number of gigs and festivals sober now, I love things like not spending a small fortune on alcohol (£6.50 a pint in some places now!) and not spending half the day queuing for that privilege as well. I also like not having to go to the toilet after every band I see...basically my time is now primarily based around the music, whereas before it was based around drinking (although don't get me wrong, it was still massively about the music too).
I will say one thing though...it is certainly a lot more noticeable now annoying drunk people are when you're sober. Not criticising one bit though as I've had almost 20 years of being like that myself.
