I always prepare before I get a tattoo-- eat a full meal, have some sugar, proper rest. But during all three of my tattoo's I've always gotten that passing out feeling-- light headed, dizzy, sweats, etc. and I always ask them to give me a little break until it goes away. A couple of my tattoos are pretty small and I've had to have one or two breaks during them because of this. Whenever it happens I always feel like I'm inconviencing and wasting the artists time and they seem to get a little aggrivated-- maybe I've just always had jerk artists, I dunno. I'm planning on getting another tattoo soon, full color and larger than any of my others. I'd like to prevent this from happening in any way possible. Is it just my nerves causing it? Is there any way I can prevent it?
