Wife fed up

No be pun intended but I have been night eating for many years. My wife and I had a talk about how it impacts her. She’s just not seen any improvement for the 4 years we have lived together. I don’t know what to do. I have tried locks with timers. Vyvanse. EMDR. Not buying anything triggering. I feel powerless over NES. How can I reassure her how can I get out of this hell loop. I wish it would stop.
