I take a ton of Armour and have to cut a pill here and there while working up to my dose. I have had no problem. I would be suspicous that what your Pharmacist gave you is maybe old? I would definately check that recall out. The pharmacy where your Prescription was filled can tell you the lot number and exp date of your medication from their records.
I do not know what type of pill cutter you have but you must cut it very fast.
I take Armour 120mg in the am and 120mg in the afternoon. I myself have not noticed any difference at all in how I feel. I only knew of the change when I read about it on here.
Also remember getting your insulin resistance under control may change your symptoms......When I first started metformin it made me feel terrible the first 2 weeks then I felt great. Many of the symptoms I thought were thyroid connected were really Insulin resistance related. I am on Janumet now which is a form of Metformin and I feel wonderful. Have been on it a year. Had PCOS when young now they call it Insulin resistance and metabolic syndrome when you get older
