The craving will keep lurking - just ignore it. Every time you ignore it, it becomes smaller and weaker...
Yes, you feel cranky & short tempered. Your brain has some actual healing to do! You will also feel dull & slow at times. Don't worry about any of it, just move through...
Eventually you'll need to get lots of sleep. Treat yourself with compassion, as though you were a small child lost in the woods for weeks without food - frightened, exhausted, starving. Eat food when you are able. Sleep when you have the opportunity. Drink water. Tuck yourself into bed with the children & take a nap...
This will all pass, and one day you wake up & are yourself again... It feels amazing, but it takes time. You almost don't notice right away, & then one day you suddenly think "hey, I feel good..."
Still thinking of you & sending good energy to you! You're doing it!!! Yaay!!
