Hi, I Have Just Started Tking Bupropion (1 150mg Per

Hi, I have just started tking bupropion (1 150mg per day) to stop smoking and I would also like to take milk thistle supplement. There is suggestion that milk thistle has an effect on the levels of bupropion (ie increases). If I take milk thistle, should I still take the 2 x 150mg bubprpion per day, reduce bupropion to 1 x 150mg, or not take milk thistle at all? many thanks
