Yes. I stopped using deodorant with aluminum around 15 years ago. I was getting sharp pains in my breast and luckily figured it out. The same with drinking coke. I was having terrible hearburn every night with only one glass at dinner. Haven’t had a coke (or pepsi) in almost a year. Of course I used deodorant all my life and drank coke too, so it’s important to realize anything can change at any time. I can’t imagine how many doctors, tests, Xrays I would have seen/undergone if I didn’t figure it out on my own. Not to mention unnecessary meds I may have been prescribed.
