Tinking away

Are you kidding? I must have spent 2 hours knitting and tinking(unknitting- tink is knit backwards) the same six rows! Ripped back to fix mistake. Success! Very long day, very tired. I couldn't get back to the pattern. My hands cramped , my arms ached, I thought I was going to pass out from thirst, but I wouldn't stop until I got back on track. I know this is a very common knitting occurence. Just gotta vent.
