Ahhhh Melon, I didn't realise you were also from the UK and I agree with absolutely everything you have said, except you missed out the red carpet for those on methadone programmes which is a particular bugbear of mine.
I have been painfully languishing in the ether of NHS waiting lists snince Sept 2008 and have only ever had blood tests. My neurologist was pregnant at my first consultation and at this rate her baby will be at school before I get a diagnosis but hey ho NHS have made their targets, I have been seen within 12weeks of my referral yipeee!
