I've had hypothyroidism for almost 20 years. But my doctor lowered the dosage on my levothyroxin, even though my test results showed my thyroid was still on the lower end. I'm still getting really tired all the time. I don't have the cold belly any more like I used to, but the lack of energy really bothers me. I'm gaining weight again, too. When I first started taking my thyroid medications, I was told to take them first thing in the morning on an empty stomach. Now I've been told to take it at night before I go to bed. I'm getting really confused about what to do. I want to trust that my doctor knows what she's doing with me, but it's all contradictory to what I've been told all these years. Please help me understand.
