Hey guys, so I don't have hypothyroidism but when I took a couple of T4 pills, I felt SO much better. I've had pretty major depression, fatigue, and no sex drive for over two years. and when I popped a T4, boom, I felt like myself again. I'll let you know that I've tried just about every antidepressant and none of them have worked for me. Now I've only taken levothyroxine once and I don't plan on continuing to use it, but why does it make me feel so much better? Here are my thyroid levels for reference.
F T4,Free(Direct) 0.95 0.93-1.60 (ng/dL)
F Triiodothyronine (T3) 90 71-180 (ng/dL)
F TSH 1.240 0.450-4.500 (uIU/mL)
