Hi there Maine76, I take curcumin(turmeric) as well but cant really comment on the dosage. I do want to bring up that I have read of some using curcumin as part of treatment for the co-infection babesia. Do you have babesia that you know of? If so, it could be causing an air hunger herx reaction maybe as it could be killing something thus affecting your breathing.
I have babesia and I cannot take aspirin so I like to think of curcumin as a win-win for me with those but I also have natural Low blood pressure and I have to watch it because curcumin gets me too low sometimes.
Maybe google 'curcumin babesia' and see what comes up if your interested...
Or heres a supportive source for anyone interested:
