Ihave had a kidney transplant 7 months ago a it is a good match, thank god, I did something really stupid last week end ,I met 2 high school buddies after 35 years and we had a weekend filled with booze, women and drugs. I did a lot of cocaine and drank alcohol, I can not explain the reason, I do not even know why, but can you please tell me if I did damage to my transplant and how can I find out, keep in mind this was the first time anfter a 25 year sober, year 1998 stopped drugs and year 2001 stopped alcohol. Please help me.
