Hello
@Carol680 welcome to the forum.
You already have several helpful replies about dealing with cravings, and re-assurance that given time the cravings will diminish, and I have also experienced this.
There is still the difficult time to cope with until you reach that situation.
If your body isn’t getting some of the things it is used to having, the brain still signals that ‘you are starving to death’ usually resulting in a craving for a particular food.
I found it useful to develop some strategies to help get through this phase without sabotaging plans too often.
Some of the things I do are:
Set a timer for 20 minutes, before taking the snack. (The craving may go away in that time as if you have just eaten it takes 20 minutes for your brain to get the signal that you are full)
Then have a list of distractions to take your mind away from the snack focus - My list has such things as phone a friend I've been meaning to contact for a while; water the plants; tidy that annoying drawer where I can never find anything etc etc.
Often I will then have forgotten about the craving by the time the timer pings. If not I'll try either a hot drink, or some fizzy water.
Mindfulness is something else I try sometimes, also thinking if there are any particular triggers that start the craving, and working out a way of coping with these.
Sometimes none of it works - then the thing to do is just to snack and move on, and don't go into self-blame.
None of us can get it right all of the time, and if we can achieve 80% or so we are doing very well.
Best wishes Carol, and please keep posting and let us know how it goes.
