I've found it occasionally helpful, but it will in no way fix procrastination -- in fact you can procrastinate (by e.g. reading through top 100 random stories on reddit) more efficiently and with fewer regrets. If you can get into the "flow" (in the psychological sense) you're able to stay there for longer and are less likely to get interrupted, but you're better off starting the day with a clear todo list and by priming things by producing, not consume (as per the recent articles).
If mixing with coffee, consume both well before you intend to sleep; I've found myself a few times in an unpleasant alert but wanting to sleep state.

In my (ahem) friends experiments with modafinil he reported the same thing, i.e. that he procrastinated with a vengeance. Last time this happened he managed to get through O'Reilly's _Mastering Algorithms in C_ in a single sitting, though it was completely unrelated to the work he was supposed to do that day.
