I have always wanted to go to Spain, it looks like such a beautiful country. My daughters did a foreign exchange when they were in high school - one went to Germany and one went to Austria, and I am still "pen pals" with the mother of the girl from Austria. You seem to speak and write English perfectly to me.
I have a ketone blood monitor but the strips are very expensive - they are $5 each! So, I only do it a few times per week and the rest of the time I use the ketostix urine test. They seem to work just as well except they don't give an exact number - just "trace" - which in me is about 0.5 and that is my most common reading with the blood ketone monitor, too. The blood ketone monitor is a "Precision Xtra" by Abbott.
I was diagnosed just after my 55th birthday and I am now 57, so we are close to the same age.
Since my kappa free light chains were in the normal range for the first time, and my doctor had taken me off Revlimid as I was fighting the kidney infection, I decided to take another month off the Revlimid and see what my blood test shows at the end of this month.
Like you, Cassy, I only take exactly what my 3 doctors (oncology, nephrology, infectious disease) have all 3 approved. I take:
400 mg Acyclovir (antiviral) twice daily - morning and evening (from Oncologist)
650 mg sodium bicarbonate (my kidney doctor has me on those because my blood has a tendency to get too acidic. I used to take 1/4 tsp baking soda dissolved in water to get the same dose)
Omega 3 (360 EPA, 240 DHA)
During the day I take 2 probiotics (Culturelle and Align or similar product from Sam's Club or Walgreens.) because I had C-diff for 6 months.(Infectious disease doctor approved these)
At dinner I take:
Cranberry concentrate (which has 700 mg cranberry) (My kidney doctor approved these).
Iron (325 mg) ferrous sulfate once a day (from kidney doctor)
Mag 64 D.R once a day - this is magnesium like Slo Mag (from kidney doctor)
Vitamin D 50,000 IU once a week - (from kidney doctor). I wonder if 20 min per day in the sun would do the same thing?

I will have to look up curcumin, sounds interesting, but like you, I do not take anything - not even a vitamin or herbal tea - without checking with my doctors first.
