Can chlorine in pool water cause you to be dizzy. I stopped smoking July 23 and started swimming at the ywca, for now 3 or 4 times a week for about 1 1/2 hours each day. In the beginning I was going everyday to keep myself busy. I'm dizzy every day now? What is your thoughts on this? My doctor had me to go to have a scan on my neck arteries at the heart hospital. Now I'm been on a 25mg a day for a little over a week now and nothing has changed,the medicine is meclizine he said if this doesn't work, next a MRI.
