Hi guys, thank you very much for the input. First off i would say my sleep hs been very interrupted. Either way too much or none at all for days on end. I'm also recovering drug addict - which i supose i should have mentioned straight off - and i suppose i was a bit worried about my concentration never fully returning properly. Basically permanent impairment from too much substance abuse. I'm hoping that's unlikely though because i can still hold a sensible conversation with people and i can talk to all you nice people on PC ok (odd typo or ten aside). But if i'm totally honest my spelling has turned really poor, very basic stuff at times i forget how to spell. When i'm writing something i have to keep checking all my words because i have such a poor memory now for spelling. I'd be embarrassed to mention some of the words i have to look up, even i think sometimes i'm glad no-one is here having to watch me check that spelling. I mean some of it really is stuff you'd expect a six year old to get right.
