Laser tattoo removal and alcohol, are there side effects, will it harm my body while its trying to get rid of the ink?

I started Picosure Laser tattoo removal about 10 weeks ago and have just had my second session. I have always worked out, eat a really good diet and drink a lot of water too. I rarely get ill, my immune system is really good and I'm a non smoker. For the last 3 weeks I've consumed around 9 units a week spread over the 7 days. My question is that I do want to go out and let off some steam here and there (averaging about once a month), but how detrimental is this to ridding my body of the ink?
