So I recently completed my first month of synthroid (88 mcg) medication (TSH-13, free t4 -0.8 range: 0.8-1.6). It's been a roller coaster with amazing ups and frightening lows. A few days into the medication, I felt like I was losing my mind. I couldn't concentrate at all and my short term memory became absolutely non existent. My balance was completely off and I used to have trouble standing at a particular place for an extended time. The funny part is that my memory/balance were better off before the therapy started. Now after almost a month I feel that my thyroid hormones have stabilised a bit and my concentration levels are slowly improving. I lost a whopping 15 kgs and my bmi now is in d healthy range.I will be going for my TSH/free T3 test in 2 weeks. Is it normal to to experience these lows at the beginning of the medication especially from a cognitive/balance standpoint? Also do I need to supplement with selenium/iron/vit D regularly and what's the best time to take synthroid...I feel taking it just before bed helps me escape some side effects. Looking forward to some expert advice.
