Chocoholic here as well
And I get such huge cravings coming up to TOM so can really relate
Some of the things I do to limit the choc cravings are
fruit dipped in chocolate, Strawberries, grapes etc. You get that chocolate taste with a bit of superspeed/free fruit as well. Syn your chocolate, melt and dip.
I freeze squares of chocolate, then can take some and suck it to death lol It lasts longer and I feel like I have had a lot more
Curly wurlys frozen makes them last longer too
Measure, chop and freeze any of your fav chocolate bars for longer lasting flavour
What is your chocolate fav? I prefer dark, it has a richer flavour so can hit the spot a lot better than milk or white varieties
Try and drink water when feeling realy hungry, as this can help fill you up, doesnt always work for me as I prowl around the cupboards trying to eat anything i can get my hands on!
I do find when I have a craving, i cant always get rid of it by subsituting with other stuff, so try and have something filling and free i.e. homemade veg soup etc. and get yourself busy and occupied doing something to take your mind off it.
Options hot chocolate is low syn, I have frozen these to eat like an icecream
Try looking at the sw recipe section, you can get some really good treat ideas that may help your sweet cravings.
I make syn free lemon curd, its delish and can take the edge off.
This with a frozen muller, some fruit and a crumbled mini meringue (1 syn) makes a really low syn eton mess
Good luck, I hope you can find something that helps you, and that your TOM cravings pass soon x
