thanks chaps.
so today i got up, had a shower etc, had some toast and relaxed for a bit, had to nip to the shop with my dad to sort the electricity reading (otherwise it would have been a pain) after this i wandered around our street but it had made me tired so i went for a lie down. cut to 6pm and i went for another wander, what would normally be a 5 minute walk took 20 minutes, i didn't mean to go that long, i got half way and realised i'd gone too far but had no choice but to continue. got home and sat down for dinner, ate, went to bed and slept for 2 plus hours, it's things like that that catch me out, a walk means sleeping!
