I use eltroxin 0.1mg every day for two years now and could not understand why I am always tired although I had a good night's sleep. I also became aware that I am very tempered, depressed and can do impulsive things. like buying a bike as example. Recently, almost a month ago I had to visit my GP for a common flu. I also asked him to run a blood test on my thyroid hormones. It became apparent that I have been taking 0.05mg less than what I should have. Could all my negative experience be because of this? I only started to take the higher doses since today, I am hoping on a better outcome. My e-mail address is Christo.***
