Hi All

I have an underactive thyroid and I'm currently on 200 mcgs per day, although its still showing as 'undertreated' and the dosage will be increased soon.

I have to say I'd suffered with it for years and years without it ever being diagnosed and the day I found out was the best ever. I've got my life back and I've lost four stone since December. This in turn has inspired me to sort out my other habit - smoking. I'm about to give up smoking, today is my last day.

However, I am concerned about the effects of quitting on my thyroxine. I've googled but can find no reference. Will it have to increase again? or will it need to decrease? Can I expect any extra side effects that those who are not on Thyroxine will not have.

Any help appreciated, thank you
