I feel yah man, right now I update 1x/week, even though I could do 2x, but I go back to school next month and I don't want to get overwhelmed and have to bump it down.
That said, staying healthy/not overworked is really important! Because if you dont give yourself enough time to work on your pages, the quality will suffer, and that will make you feel worse about your work and then you'll want to work on it less and that will make you procrastinate which will give you less time to work which will make your pages suffer which will make you want to work less... you get the point.
It's a downward spiral.
The people who update a ton of pages each week usually either do comics full time, don't have a social life, or some combination of both. It's not the healthiest situation to be in.
