I have Hypothyroidism since I was 16 (I am 29 now) and have been taking Synthroid ever since. My prescribed dose has been 100mg a day; however, recently, I am feeling like this is not working. I am tired and sleepy all the time. I tried taking 200mg daily instead and I have more energy and feel completely fine. I went to the doctor and had blood work done before increasing the dose (by myself, not doctor prescribed) and apparently everything is fine but I can't believe it as I don't function if I only take 100mg.
is it bad that I am taking a higher dose even if I feel better and function normally?
