My Long Tattoo Removal Process

I have been getting laser treatments for the last 13 months. It's going much slower than I thought it would. I have already received 7 treatments for each of the 3 tats I am removing. I am wondering if it was worth it and whether or not these tattoos will ever come off. The laser is a Cutera Enlighten. The doc started very conservatively with low fluence settings and I started keeping track at the 4th treatment as follows: Around the 4th treatment we were at level 4 for fluence and gradually worked up to where we are now at the 7th treatment with a fluence level of 6.5 and 8.5 depending on the tattoo.
