High bilirubin. Than 3-4 units per day?

Hello, i want to ask something about high bilirubin. In short, i use to drink beer for the last 1-1,5-2 years (3 bottles a day, 0,5L 5% alcohol each, for 5 days a week). In 26 August i make my blood tests. Sgpt, Sgot, Ggt and all the other parameters were very Ok but total bilirubun was high, 1,83 mg/dL with direct bilirubin(conjugated) 0,62 mg/dL and indirect bilirubin(unconjugated) 1,21 mg/dL. I was waiting  high bilirubin because i have Gilbert Syndrome but  the indirect bilirubin to be high not the direct bilirubin. So i decided to cut off drinking and make the exams after 1 month. In this month i took milk thistle too. In 26 September i remake the blood tests. Direct bilirubin was again high, 0,58 mg/dL with indirect being 1,11 mg/dL. I was told that in some cases Gilbert Syndrome can higher direct bilirubin too. Now i want to ask, can i drink some light beer 3,5-3,8% alcohol within the barrier of 12-13 UK unit per week. 3-4 days a week with no more than 3-4 units per day?Thanks
