Splenda-man 

Sugar daddy lite.

My sugar daddy lost so much money in the stock market that he is more like a splenda-man these days.

Splenda man 

The guy who comes into your house at night and replaces all your sugar with Splenda brand artificial sweetener.

Guy 1: Dude, where's the sugar?
Guy 2: We're all out; the Splenda man visited last night.
