I used AVRT at times like that. It's just the addictive voice so I acknowledged it and didn't give it much head space. It's to be expected and it'll pass.
I'd also be a little impatient with myself (doesn't work for everyone) but just kind of 'cop on. you're not 2. you can want something and not have it. it's not all about you'. That helped.
In time I started to crave other things. Now, I crave a new tea or hot chocolate. Or the gym. Or chocolate. Lots of different treats.
It's tough though I remember! Sometimes hour by hour. But it DOES pass. I'm only 4 months in and cravings are very very rare for me now.
