They pick the worst time to switch...
I'm really, really, not fond of Daylight Savings. I'm at my most effective in the morning -- in fact, these days it's about the only time I can get effective revision done -- so losing those few hours because my internal clock is screwed up is not good at all. After I get home from school I'm often unable to focus (case in point being this afternoon, where I was barely about to remember my own name and had to pass out for two hours in order to regain some brainpower), so there's no chance of me getting anything substantial done before dinner, and after dinner usually brings TV. Which leaves me with very little to show for my evenings.
I'll have to work something out. I hope that I'll be able to get back into my routine before too much longer, otherwise these next couple of weeks are going to be more stressful than they strictly have to be.
