Disaster. I moved to Seville last week, and my Anki reviews simply stopped due to the lots of things I had to do. I had literally no time at all to do the reviews. I tried to do a few, and I managed to do 10-20 a day (I slept between 4-6 hours a day, so I didn't want to screw up more). Now I'm back home for holidays, and I had to review 2XX kanjis. It's a nightmare, my failure percentage is about 40%-50%, and I will have to review a lot in the following weeks to cover up.
Conclusion: Never, ever, stop reviewing with anki if you can. I had forgotten most of the kanji that I had to review early last week, because instead of remembering them 5 days (or whatever) after the last review, I'm trying to remember them after 12 days. And of course, I don't remember most of them, so I have to start again (somewhat). I don't have this problem with some easy kanjis, or kanjis that I had already failed and I'm re-remembering now, or very old kanjis that are due in 2-4 months, but still, it's very discouraging.
But well, at least the reasons are good: I have a job, it's a very good one, I moved to another city with my girlfriend and we already found a house to live in (and in a very good place), so I'm not complaining!
