Oh, one other way I know I'm having mild withdrawals/cravings:
Last night I felt absolutely starving! Luckily I filled the fridge with carrots, peppers, yogurt, rice chips, hummus, etc... so I just gorged on all of that instead of junk food. But, yeah, I was craving snacks as much as I did on previous, cold turkey quit attempts.
I think I've adjusted today.
I had sliced red and orange peppers with yogurt for breakfast. I bought a lamb gyro pita for lunch - it's a pita stuffed with lettuce, tomato, and tzatziki sauce - with cooked meat, mushrooms, onion and green peppers. Delicious - and relatively healthy. It doesn't come with any side dishes, either, so those are some calories not consumed.
And, right now, for a snack I'm having some more yogurt.
Going well.
I also quit Diet Pepsi yesterday. I haven't had one since Tuesday evening. I usually drank up to 3L/day.
And I don't feel overwhelmed at all. I'd have to force myself to quit drinking Diet Pepsi, really, I'm so anxious to just be rid of all these unhealthy habits.
Woohoo!
