School residential trip tomorrow

So tomorrow I am heading away for an overnight trip with my Form 1 tutor group. Should be a good laugh, certainly different from sitting in a classroom all day anyway. I don't know how I'm going to manage tiredness wise though. At the moment I'm needing to get home and have a wee sleep as soon as I get in and before I even think about whawt's happening that evening (my husband does the cooking mostly, so that's one less thing to worry about, in general), so being away for 2 days will be quite tough. I'm consideirng bedding down in my store today for a wee lunch time nap. The monring up to breaktime is bearable, but break is too short to be particularly re-energising, so that double lesson leading up to lunch will be tough today. This time tomorrow I'll have arrived at the outdoor pursuits place, and probably have been dragged in to a canoe by now :) I just hope to god they all sleep tomorrow night, as I've been asleep sound from 10 until half 6 recently, and I dread to think how I'll cope on Wednesday if they keep me up all night!
