I put sleep at the top of my list, too. Definitely. I am just past 11 mo (28 days til one year!!) and I still find this is HUGE.
From what I have read and been taught, it (can take) takes the body one to two years to heal itself, particularly if you were severely alcoholic like me.
Eating at first was a challenge and I needed to gain weight. I gave myself a VERY long runway once the sugar cravings really hit - so from about 60 days till 2 weeks ago ice cream was a common companion- although the rest of my diet is excellent. I started running a little in May and in the past two months have done 5Ks; I also started a very active job (a restaurant with four flights of stairs) in Aug.
And, truthfully, time. Time is the biggest healer of all.
