Looking for professional advice?

For the past 2 weeks, I have felt a mild pressure on my right side, around the rib cage area. My bowel movements have also changed a bit. I finally went to the doctors office and he ordered a set of blood work and an ultrasound on my upper right quadrant. He called me with results today...ALL the blood work results were normal and all the organs in the ultrasound were normal, EXCEPT for a mildly enlarged liver. All he told me was to "watch my alcohol consumption". I'm getting married in 3 weeks so there has been a lot of partying the past few weeks. I'm just trying to figure out if there is away to reverse this or is this something that I gotta live with. I also had some tooth issue about a month ago and I was swallowing ibuprofen like candy, and sometimes on an empty stomach...Just looking for some insight, not criticism!!
