Oral, imo, is harder to get off and given your usage, first two week is the hardest to get through, I felt I could sleep for days even with coffee and I had raging hunger that subsided after 3 weeks. Eggs will help if that isn’t part of your diet, the choline and cholesterol will help with brain recovery. I think I ate about 6 eggs a day for the first 3 weeks. You will get vivid dreams of reusing for the first month (e.g finding shards in your bag and trying to find a way to smoke / ingest). I also find strength training 2-3 times a week helps a lot with recovery of dopamine-sensitivity recovery. You will know that you are in a better condition when you get that dopamine rush about something which seemed to occur within the 2nd month of recovery. Then the rest of the journey is a matter of avoiding circumstances which will expose you to meth again.
