Back in 1986, at age 19 in Canada, I was diagnosed with hyperthyroidism. I was prescribed a pale green pill, that had a confetti=type multi colored speckles on it. The pill shape was many sided, with either 6, 7 or 8 sides. I had to take it twice a day, and for about 30 days. I have searched pill ID visually and can't find it. Does anyone have any idea what this was?
