Congrats on 29 hours!!
I'm trying, too. I am 42 and TTC and I have heard that sugar is a fertility-buster. Big motivation there, at least. Everyone talks about how healthy my diet is. It's true I don't drink soda or eat actual candy, but I've never met a homemade cookie or chocolate I didn't like. It's still sugar! Plus I have an ice cream maker.
My strategy is to absolutely spoil myself with the other foods I really love. For me that's bean dips, sweet potato and beet chips, guacamole...all home-made, etc. I am stocking the freezer and cupboard.
I've found that I really want a sweet break midafternoon, before I go pick up dd from school. So I am having a decaf coffee (giving up caffeine, too!) and one dark chocolate, fair-trade vegan Easter egg. When those are gone...

I would say make a list of all the absolutely fantastic other foods that are a true treat for you and splurge on them, if you can. I have been sticking to my plan for 3 whole days.

So is this the sugar-free support thread?
