THAT has been my delemma for the last 15 years! I feel like I'm now made of glass, and fragile stuff at that. BUT? I went with the seemingly best 'conventional' wisdom at the time also the safest known then, and I also knew the possible pitfalls. I GOT revenge in ACES!
I feel that my 'auto-immune and immune' problems that developed almost concurrently were complicating factors as THEY weren't as promptly diagnosed as could have been more beneficial in the long term.
Result? I definitely NO LONGER WALK ON OR DEAL WITH ICE in any shape or form. My last fall was disastrous, if not catastrophic.
Soo, what to do? Try something 'new'? or just scrap it all! THAT is an individual choice and only YOU can make it... just know all the pros and cons before deciding. It all can't be 'undone' later!
I hope that that whole heap of Mrs D's researches can and does help you decide and that you also come out of all that reading able to speak in complete sentences! You all know what I mean!
Hugs and hope? Always! - j
