I’m with you; I’ve gotten “advice” from supposedly well intentioned folks who are completely clueless about my medical condition(s) yet seem to feel like experts on supplements/medications , exercises, and diet that would be best for me. I have found this forum of experienced folks a qualified source of advice, and then I do have to credit doctors for the medical education and learnings they share with us and help in our disease management. I don’t need to listen to the ignorant.
I try to just change the subject on those folks, who are usually family or great friends! If they continue, I respond with something like “I’m glad that works for your Neuropathy” (which they don’t have) or “I’m working with my doctor right now but can see what he thinks about your ideas on my next visit.” Yet, for folks who may see the inside of my home or venture through our personal areas, I keep bottles of OTC vitamins separate from my prescription medication bottles to help keep the judging of my prescribed medicines down. Sadly, I only keep one bottle of each prescribed medicine there; refills or excess bottles due to 90 day supplies (like the 6 bottles of Gabapentin I get each quarter) are buried deeper somewhere. I resorted to that because a relative went all bat crazy with lectures once when I pulled my drawer out to refill my weekly pill container, so it’s easier for me to hide the extra supply so I don’t have to deal with explaining the “quantity” of pills I take. We’ll never fix them, so I try hard to avoid the conversations, which of course you already know is one-sided with these know-it-alls.
