Health Check Up. Your time n help!

I have been consuming alcohol on regular basis for the past 6 years in large quantities. I weigh 102 Kgs with a normal height. I do not eat healthy, mostly outside foods usually very late at night (e.g 2 Am). I also do not have a proper regular sleep. I am a very light sleeper, generally 4 or 5 hours max a day for many years now. I feel tired everyday. I have no health issues so far except lack of sleep. Please suggest me on the check ups that r required for me to make sure all my vital organs are safe like heart, liver, kidney, lungs, pancreas etc. I have a small lump inside of my right side of the stomach. 4 years back I had my stomach checked and I was told it was lipoma and I shouldn't worry about it. I have had no pain in that area but I can always feel it. I can feel similar smaller ones in 4 other different areas too like one in my chest area and the rest in stomach. Please suggest me all the tests required. Would really appreciate your time n help Thanks in advance.
