V'rap - I'm not that far away, what do I have to do to get on your list:-)
I've had to fight for the best part of three years to get to the 100mcg I'm on now - and only got that after my lovely GP diagnosed me as having CFS (despite me marathon training) and referred me to the CFS clinic who talked to me said 'your thyroxine levels are too low, what's the problem?' and wrote to my doc to say the same. All of a sudden I wasn't a depressive looking for an excuse and whingeing all the time but someone who needed double the dose I had been kept on for two years! I'm still only 1.67 so room for manouvre but I don't feel bad enough to fight again just yet.
Ian - do you find that you're mentally tired too, a kind of foggy brain? Difficulty remembering things or concentrating?
