I took the Centrum late at night with dinner (to avoid interference with the levo
in the morning).
The Centrum gave me chest pains and other discomfort. So, I stopped taking
the Centrum. After I stopped taking the Centrum (and during the last few weeks of this 8-week period), my hypothyroidism symptoms came back (soreness in arms and legs, other symptoms).
After that 8-week period of 125-mcg levo, my blood test was as follows:
TSH = 1.919, and Free T4 = 1.
