Bizi, I had issues with sleep and alcohol cravings, too. Somewhere between the amino acids, the magnesium, and (I think a big part) the neurofeedback, I'm much improved over the past year. The neurofeedback particularly has given me what feels like insulation between the stimuli of the world and my internalization of those stimuli. Things that used to trigger symptoms of depression or anxiety no longer do, or at least my reactions seem in scale with the stimuli more. I don't know if this is available around where you live, but I am so eternally grateful to have found it here. It really made an enormous difference for me. I think not living in a constant fight/flight/freeze state with my nervous system has made an enormous improvement for my sleep and decreased my alcohol cravings significantly. You might check with your care provider to see if you have access to neurofeedback where you live?
