heart palpitations, nervousness, dizziness when bending over, erratic sleep that seemed like it might be a blood sugar problem, and muscle spasms. I had been doing well on 50 mcg T4 and 25 mcg T3 from Mylan
labs for about a year. I cut the T3 in 1/2 w/ Dr.'s permission. In about 5 days, those symptoms went away, only to be replaced with crushing depression and brain fog as well as difficulty focusing my eyes. WHAM!! After 3 weeks, I had gained 15 lbs.
