This used to happen to me almost every day! It's eased off now I've started SW again but sometimes I do still get that sweet craving, even when I'm stuffed! Fruit or yogurt don't cut it for me unfortunately. Last night I had half a pot of Total 0% with a tsp of sweetner and that was so sweet it made me feel sick enough to put me off of anything else for the evening

(Feeling sick wasn't my objective, I just had half a pot leftover from dinner and wondered what it'd be like with a bit of sweetner). Other times I have a few jelly beans (5 for 1 syn) or a Freddo bar (2 syns) to satisfy my craving and that usually works. A banana with a 1 syn drizzle of syrup also hits the spot nicely and feels better because it has fruit in it

The only way I can think of to beat it completely is willpower...not always the easiest solution though! Maybe black tea with sweetner for a free alternative? (May not work though as most people hate tea without milk...but I can't stand milk in my tea, makes me gag lol).
