I faint reguarly after donation. Just a got low sugar levels, whatever I do I can't stop it ( eating 15 Mars bars and 20 bottles of Lucozade ), but now they know I do it, they lie me down and just let me go. And I tell you, it's the best trip ever. Better than any drug I've tried, you go into a maaaaaaad world for about ten seconds and I ALWAYS come out of beaming like a beaned up 16 year lad from Huddersfield after a Scooter concert. It's AMAZING.
