Does anyone else experience short term fixations?

I’ve had this throughout my life, and its mostly evident when food is concerned but I am sure it might be in other areas but none spring straight to mind.

I was wondering if anyone else experienced short term fixations on some sort of object. For example for me, I tend to have about 1–2 weeks where I really like one sort of food and tend to focus on eating that (but not abnormally like eating it every single day, just more than average in the whole year). At the moment it is pizza. I haven’t eaten pizza for about 3 months, but in the last week I have made 4 ever since I had discovered how to make them from dough and jar sauces. I also generally always have something that I am fixated on, but perhaps a week gap between transitioning.

Another area that this might be happening in is music where I generally enjoy listening to a band for about a month or two and then switch and not really listen to them any more for probably a 6 months to a year.

I know this is probably just operating under the principles that 1. you tend to like new stuff better than more familiar stuff and 2. too much of something wears on you and leads to a repeat back to step 1. But I was wondering if anyone else has noticed this in their behaviour.

Discuss.

/edit In fact I think I just answered what was happening in the final paragraph, but nevertheless do you experience this sort of thing any ways?
