Honestly, I have the same issue. Once I started eating 90%-100% cacao bars, it satisfied my cravings. Coffee, cinnamon and chewing on ginger root helps a ton. Maybe it could be the earthly flavors chocolate offers that calms you when you are stressed. Chocolate also had caffeine and activates a feel good hormone in your body, which could be alleviating your stress.
I thought Dark Chocolate was okay in proportion? I have been melting dark chocolate and covering oranges, bananas, cranberries, walnuts and almonds. the most delicious one was Almond butter covered in chocolate! yum. But Cranberries are pretty good and almond butter has a satisfying taste. Look up paleo candy or treats, find some recipes :)
Actually, I supplement with Magnesium when I have chocolate cravings. I wish I could be more helpful on a research front (anyone help a friend out there?), but I did read somewhere that chocolate contains a decent amount of magnesium and that my cravings could stem from a deficiency. Hopefully a smarter, savvier fella out there can correct me if I'm wrong. Anyway, experimenting with it has really helped to curb my cravings a ton. And I'm one of those "can't go a day without eating a bite of chocolate" kinds of people.
Lately I've realised that my chocolate cravings were because of the chocolate, not the sugar that's in it, so I started drinking two tablespoons of cocoa dissolved in a cup of hot water. It's a bit bitter, and for some it might be an acquired taste, but I love it.
Satsumas are nice. The peeling process slows you down a bit (more of a food ceremony) and they can be very sweet. I spring for the organic ones, always, and only buy if they actually are fragrant. Most conventional ones are very lackluster.
Oh! A Moroccan style treat - orange slices (horizontally - peel than slice with a knife) sprinkled with cinnamon and orange blossom water. Infinitely more decadent than orange segments plain.
My first solution is to make my own chocolate bombs: coconut oil, 100% cocoa powder, and whatever else I feel like adding. Last night it was coconut, cashews, and a tiny bit of coconut sugar. Last time it was raspberries and a bunch of other stuff. The result is a super-chocolately treat with minimal sugar; somehow this satisfies me and one serving ends my chocolate craving.
Solution number two is the energy bars I make (no chocolate in those) - the recipe is on Mark's Daily Apple. I modify them every time I make them, and they're so yummy! One serving is enough.
Maybe you could try just not buying more than a small piece at a time so you have to go walk to a shop in order to get more each time. Having a big bag o' deliciousness sitting next to you is gonna be psychologically taxing, no matter what it is.
I think switching from morsels to bars, and the highest cacao rating you can stand, will be the best choice. It's more work to eat a bar since you need to break off pieces (assuming you don't just bite it off). It's so easy to toss a handful of morsels in your mouth. Anything that makes eating mindful is good.
I eat chocolate, but I always eat it with fresh fruit, never alone. Citrus works well. So do cherries. Dates are fine, but awfully sugar-dense. Lately I've enjoyed frozen grapes, and frozen tart cherries as sweet treats, with or without chocolate!
I melt equal parts coconut oil together with unsweetenened cocoa powder and use stevia to sweeten. I have liquid vanilla creme stevia, but any kind works. Pop it in the freezer for fifteen minutes and break off a piece whenever you need it. Small quantities obviously are better, but it s a healthy alternative and it's quite decadent.
