My doctor has me taking Westhroid, which is similar to Armour. (A natural thyroid product). He has me taking it twice a day. I only take 1/2 tablet in the morning and the other half late afternoon. My doctor wanted me to take it later in the evening, but I found I had too much in my system in the early morning (heart racing) and it started affecting my sleep. I would try it once and see how your body reacts. Everyone is different.
P.S. I use a pill splitter to make sure the doses are even.
I've heard of people splitting their dose. Maybe you could try that!
