For a moment, I thought the exchange between myself and flounderguy guy put the doubt to bed. What conditions did his and my case share? I can't claim that my bottles containing the cracked pills were ever exposed to very hot temperatures. It may have before they shipped to the pharmacy, or the mail order distributor. Our cracked pills had for a period been in bottles that were closed. If those two conditions are replicated, we should see the same result. I agree with JL, the pills are made very durable. However, obviously, not enough to prevent me from living through two episodes.
