The issue you're having is due to the fact that Anki "Accumulates" cards if you skip one day, which can build up and create such a large amount of scheduled cards for a day that you end up dropping the thing. I'm working on a spaced repetition algorithm that solves this issue by letting you review when you have time and letting you skip the days you can't do the reviews.

I'm interested! I've noticed exactly this. But also even with regular use I've had times where the stack and thus required study time was just ever increasing. This is probably a mix of too many new cards plus high difficulty resulting too many reset cards. It would be great if I could determine when and how long I'd study and the algorithm would just offer me the cards best to study next, being repeats or new ones. That would combine nicely with a 'dont brake the chain' or other habbit forming technique. I'd prefer a daily n minutes above something that may take increasingly longer.
