Can't you get them for more like $25-$35? Have you checked Cousins Maine Lobster? I know, still a high price, but every bit helps when you can't resist the craving...the average price of a lobster roll in Maine is $30-40, way too expensive for me to eat with any frequency.
I mainly eat turkey on whole grain bread with romaine, honey mustard, and olive oil mayo lately. The tryptophan greatly helps combat the noisy neighbor situation that's been going on above me for well over 3 years now. A slight caveat is I often doze off while watching movies or even gaming sometimes, especially if I'm up too late.
