I suffer from lax abuse, I've tried quitting but I've only been able to reduce from 10+ a day to 2 or I get v sick. I'm having lipo, will this cause issues?

Probably not but. it would be very important to reveal this to the surgeon performing the liposuction BEFORE the procedure is done. Call and let them know so that they can confirm your metabolic status and electrolytes are ok and it is safe for you to receive anesthetics.
