I have to have a medical will i pass???

I got banned again due to the twice in 10yr offence. I am what they call a HRO. I took the Drink awareness course and was told by the instructor that if your a regular drinker to cut down to 1 pint or glass of wine a day for at least 6 weeks before your medical. I've also read in some bloggs posted that the test is affected by paracetamol, as i have broken both my shoulder's and my foot Oh and a couple of Ribs over the past 5yrs ( all due to coaching Girls football lol) i take anti imflammatory tablets and painkillers daily, will this also affect the medical???
