i know just too good what you mean. if you ask me, the real question is not what to do when you can´t sleep, but what to do before you get to sleep. as you say, you´re thinking about your product(s), features, business plans, the next steps,... the best thing is, at some point i´d say at least 30min before you wanna go to bed) you have to stop. stop thinking about whatever you work. stop thinking about future stuff. and start to relax. read a book. get out with friends (even if its just for an hour). perhaps you might think that this is time you need for developing ideas, plan stuff... perhaps it is, BUT your (mine too of course) performance in the night sucks, and if you can´t sleep your tired the next day and then your performance sucks too. another point is that you can´t work all day and night forever. i had a day that summer when i realised that all the work i´m doing is bullshit and i´d rather stop today than tomorrow. so i took some days off... don´t let it get that far. and most important: have fun (outside work too)
