Do you like cheese? I know you say you don't eat it often but... a great way to have cheese is by having 3 (check your book) light babybels as a snack at work etc. 
 
Also - You don't HAVE to have 2a's, I normally just have one. 
 
One last idea - how about using milk to make a lovely options (2 syns) hot chocolate in the evening? x
