i am a regular beer drinker. i have had 3 stents i currently take bisoprolol.amlodipine and allopurinol i often get feelings of light headiness as if air has suddenly escaped from a balloon, followed by a cold sweat, should i ask for a review of the tablete i take or simply cut out beer. difficult for me as i run pub quizzes and im also a rugby coach, with all that intails post training and post match
