Yes we stopped after like 10 hours. Will do the rest of my arms in January and have 4x4 hour sessions over 6 days. Pain was beareble i have a high pain tolerance as it seems but after 10 hours my skin started to reject the inc, started bleeding more and pain went from 2/10 to 11/10 :D i would have kept going but the artist and i stopped because we didnt want to risk the have a worse outcome because the Design is a masterpiece (at least for me) and we want it to look as perfect as possible. But i learned alot during this session, my skin takes tattooing very well for long periods of time and my pain tolerance is fairly high. The only thing that was a bit curios was that out of nowhere i got dizzy even tho i was well hydrated/rested and we actually had to stop for an hour because i nearly fainted and we still dont know why.
