I am also terrible with snacks, don't really enjoy cheese that much. Sometimes I just make a smaller meal. But I really enjoy string cheese, cut up and microwaved for about a minute, it ends up crunchy! And I eat that with pickles.
I find that salads or dill pickles help me stay on track with my snacks. Also, if you're living with someone who is not on the plan with you, try to schedule snack times near theirs so you aren't tempted. Most cravings will go away with having something in your mouth, chew multiple times and think of how much work you'd have to do to take off the extra unneeded calories that the other person is consuming.
Drink water, flavored water if it's sweets that you're craving. Hunger is often mistaken for thirst.
Alas, we all have a desire (especially certain times of the month for some of us) to indulge in chocolate. With the allotted 75-100 calories of leeway for treats, I suggest consuming dark chocolate (70% +) this has the added benefits everyone is talking about. I personally LOVE dark chocolate, the darker the better (also keep in mind the darker the more bitter) but you can get used to it!
