If you think your body is going to have any problem with it ... sleep in an hour (by the clock) ... :-) ...
If you actually do have a problem past two or three days, I would advise going in and seeing your doctor.
My body has NEVER been able to adjust to the stupid DST and I know other people who have the same problem. It is NOTHING that any doctor sees as a “problem”, nor can it be “fixed”.
It would benefit you to not talk about things you neither know nor understand.
