Hi there. I'd like to find out about medication during fasting.
I'd like to try the 1 meal a day / dinner to dinner / +-22 hours fasting.
I take 1 Eltroxin for Hypothyroidism in the morning with 1 Tareg for High Blood Pressure.
I also take Glucophage for insulin deficiency and Puricos for high uric acid in the evenings after my dinner.
Will the morning pills affect my fasting and is it safe to have with a full days empty stomach?
Thank you!

Taking medication is more important than being concerned about breaking a fast. Please consult with your doctor about medication dosage and timing.
