Hi. I had my thyroid removed 9 years ago after a multinodular goitre became very overactive. I was on Thyroxine before and have been ever since. My GP at the time put me on 200mg daily a dose I was on until I changed surgeries. After a full mot new GP said I was on too high a dose of Levothyroxine and has been reducing it every six weeks after blood tests. I am now on 125 mg and am feeling dreadful. Rapid heartbeat. Shaking. Notsleeping but feeling ( and being noticed by others as) tired all the time. Very depressed and no energy to do anything. Has anyone else suffered withdrawal symptoms like this and will it get better as my body gets used to it. I had a brain tumour removed 14 months ago and this was scanned in december and doesnt seem to be a problem at the moment.
