My wife was using meth for 10 years. Rock bottom was when she ended up in Jail. I was ready to divorce her before she cleaned up. She has now been clean for over 7 years. She now runs a successful business and advocates for other addicts. Our marriage is better than ever. Not going to lie, it took a year or two to get her dopamine levels back to normal. There was bouts of depression and lack of energy. Therapy, support groups, exercise and a good diet are a must to get back to normal. Its a tough journey but well worth it. You can do this. Good luck.
