If you have a structured schedule (it sounds like you don't)
If you mean me, I do have structured schedules, but they are not the same every day by any means.
It also helps with depression induced by lack of light.
The only way to get over that is to try to take advantage, as best one can, of the amount of daylight that there is at any given time; changing the clocks doesn't acheve that.
It would be much more complicated to have everybody adjust their schedule to take advantage of when the sun is out, to say it in Ptolomeic terms.
But we all do this already in any case - not ALL the time, admittedly, but a lot of the time - quite simply because at certain times of year there is more daylight per day than at others. For the most extreme example of this, consider what it is like for people in the north of Scandinavia where, for part of a brief summer, there is almost no darkness and, for part of a long winter, there is hardly any daylight at all.
Best,
