Was going to do my 4th dive on a Sunday, aff cat c, very raw to the sport, excited as hell but partied too much Sat. evening. Got to the DZ, sat in the truck questioning how I "FELT". My heart wanted to go but my head told me not to. I watched as the plane was headed to the wash rack and I headed home feeling like crap that I didn't go and hungover! It just didn't feel right so don't second guess yourself. I would have probably wasted my dive or even worse. Trust your gut and err on the safe side. Blue skies.. Party like it's $19.99
