I gave while on LT. I have low BP so usually have to be careful about getting uptoo quickly so I just asked them if I could lay down for a couple of minutes and I was fine. A friend questioned whether you should give whilst on LT so I rang them up and they said there was no problem with donating. Just be careful not to stand up too quickly and take it easy afterwards (and resist the biscuits!!!!)
Thanks cuddlyfairy, thats good. i think ill leave it another week or so before i go but ill definately do it.... tho it wont be the same not having a nice sweet cuppa and orange club biscuit after lol!!
