in the next few days I'll try to track down the doctor in Cork my wife went to, he arranged all the tests and diagnosed her with Cronic Fatigue (basically all the tests came back clear and then they call it chronic fatigue, as far as I know).
I'm in the Crohns section too...
I'm interested to know if you were on Imuran when you 'crashed',
I had to tell my specialist I was coming off the Imuran as I was totally wrecked, unable to sleep and extreemely tired, I perked up the very next day (not totally, but loads better), to my wifes delight as she's having a bad patch with the CF and I was able to help around the house for once.
