I am 22 and been on generic
synthroid for 4 years now. I just realized why I had crazy headaches and
nausea every time I missed two or more doses. The withdral symptoms I have include headaches extending from the back of the head to the right and front of the head, loss of balance & coordination, nausea, severe brain fog, difficulty with concentration and speech (slow thought process), memory loss, sensitivity to light, muscle pain, fatigue, moods get worse, and feeling like I will pass out!
