Need a recipe for Low-Carb Cheesecake...

i have a HUGE problem, my mother-in-law has been on the low-carb diet for years now & LOVES the recipe she had for Low-Carb Cheesecake...
recently my own mother found out she had Diabetes & asked about getting the recipe for this cheesecake (since it would be better for her than the regular version). the problem is my mother-in-law gave me the recipe to copy & i lost it!!! i have been desperately searching the web for a similar recipe & i can't seem to find one!
it was a no-bake recipe & had some kind of crushed chocolate cookies or crackers or something on the bottom, but not melted chocolate...there was a crumb crust....
can anyone help with any kind of similar recipe??!!!
THANKS!
