of Crohn's and food cravings

When I was small -- and even during gymnastics when I had to carbo-load and be careful about protein and sugar balance -- I never had issues with food cravings.  That was an adult-onset thing.  Alternatively, it could have been a Prednisone-induced phenomenon.  Although it's well known that part of Prednisone Mania can include enhanced sweet tooth and weird food cravings during regimen, there seems to be no accessible record of either long term effects of these sort.  Then again, I haven't looked very scrupulously...

That I [and my medical journal of poo's and drugs] can recall, I started to have food cravings beginning after my first encounter with Prednisone when I was 16 (notice that I categorize 16 as "adult-onset").  Since then, I've only ever not had some degree of craving when I was nauseous.  Usually this is just a sweet tooth, but in my later years it has become refined to sushi, curries and Teriyaki chicken burgers*.  I have also expatiated on my inability to ignore food after a run to the grocery store, when the fridge and cupboards are replenished with veritable goodness.

In the past month, however, my cravings have subsided -- even in the [natural or coffee-induced] absence of nausea!  This is very uncharacteristic and, so far as I can surmise, unprovoked.  Am I just getting old?  Am I evolving from a stress-eater to a stress-starver?

*as an aside, why doesn't Google know how to spell Teriyaki?
