Just to say, I am feeling my whole self again. I don't know what everyone else thinks of getting any better but I think it's down to good Consultations and hospital work with referalls near the end and a good doctor. I had an overactive thyroid which got treated with carbimazole but it came back within a year and then was back on carbimazole until they gave me RAI. That got me well but sent me severely underactive and had to be put on Levothyroxine. I am now just about on the right amount of Levothyroxine and am feeling so well. I have to take 150mcg a day. Whatever your situation if it's properly treated hold in there because you will get better and you will feel so great again, I've been ill for about 3 years but in the end it was worth the wait but a bit long.
