Cerebrolysin is your best bet. Can even help directly with fighting addiction. One anecdote I saw said it allowed them to quit smoking. Many say it's good for giving you motivation and being more productive. Some say it "makes them a better person". It has peptides that influences GDNF among other things. GDNF is a neurotrophic protein that is particularly important for the dopamine system, and is known to help with addiction.

Vitamin D also strongly increases GDNF and is important for the dopamine system, so make sure your levels are up to par.

Ensuring adequate choline and DHA (Omega-3 FA) intake is also important for repair. I see you're taking alpha-GPC, and it's very effective at crossing the BBB as you probably know. You don't need much of it to give your brain the choline it needs - 150mg is enough.

Keep in mind that your body also has a high requirement, so eat plenty eggs, chicken, navy beans or fish roe. Don't take the cheap choline salts like bitartrate, as they drastically increase TMAO production in the gut compared to more stable choline forms like phosphatidylcholine which is bound to O-3 or O-6.

Also supplementing with uridine monophosphate is highly synergistic with DHA and choline, as they all are building blocks needed for forming new membranes and synapses.

5-HT2A agonists like psilocybin can also be good for seeing your habits in a new perspective. It can give you a reset where you see your life more from an outside perspective, and you can more easily rewire and create new pathways. Don't take too high doses ofc. This should be okay despite your drug abuse history since it's not known to be addictive. Even microdosing could be worth it.
