I'm at my wit's end with my health. The endo says my ft4 & ft3 are great, and despite having high cortisol for 3 of the 4 saliva tests, he wasn't interested. I suffer from anxiety anyway and started a stressful job in December. My insomnia has got so bad now. My skin and eyes are dry and itchy, but I'm not losing hair and my bowels are ok. I can't lose weight and my temperature is consistently low. Now I'm losing my appetite in the evening, which may be because I'm so tired from not sleeping. Jumpy at noise, tearful, ringing, congested ears. My heart rate isn't too bad (68) as it was 60 originally. My joints are stiff and my hands can tremble. I know anxiety can cause some of these symptoms. It's so hard to know what to do. Do I increase from 2.5 grains (split into 2 doses). I do take good quality supplements, including all the important blood nutrients, D3, magnesium etc. Sorry for constantly moaning.
