u shouldnt take any vitamin tablets two weeks before the op as aparently they thin the blood, get as much rest as you can eat as much natural vitamins as you can get the antibiotix done and hope for 3rd time lucky i was on antibiotix till the day before my op but i never told them . so long as it does not go to your chest and effect your breathing you should be fine, ps when i get tonsilitas wich is a lot i find drinking hot blacurrent helps sooth it x
