swantje, when i came over it was similar for me - all those enticing english sweets especially. the things you just don't get easily in other places but which you love because you used to get them as special treats when you were a child...
so you have learned to get them whenever you have an opportunity, because opportunities are rare...
and now all of a sudden, there are muffins etc. every place you look. soooo dangerous!
however i found that after a month or so, i was finding most things plain bland. i found that while all those muffins really look appealing, there are in fact only few which live up to my expectations. so, after eating myself through a whole lot of muffins (etc.) in the beginning, i now find it lots easier to retain myself...
