I recently quit cocaine 2 weeks ago after 2 years of cocaine use when I first noticed memory, learning, problem solving, and concentration impairments while performing job functions on the job. My job requires alot of analytical thinking and analysis of information. My average intake during those 2 years was 3 grams/week. I became very nervous and stressed 2 weeks ago because the simplest assignments and tasks at work would confuse me. In response, to boost memory and concentration, I purchased choline, DHA, ginkgo, and Phosphatidylserine. In addition, I read that cocaine damages neurotransmitters and depletes serotonin and dopamine so I had purchased 5htp, dlpa, L tyrosine, glutamine, multivitamins, fish oil, B-6, B-12, and whey protein. After 2 weeks of taking the aminos and supplements, I've noticed noticable improvements in brain function 3 days ago. I feel relieved that progress has been made as my memory, analytical thought, and problem solving skills have improved. Progress but the functions arent fully restored. What exactly is damaged that causes these impairments from cocaine use? Are aminos and supplements used to repair these damages? Can the damage be reversed from prolonged abstinence, aminos, and supplement intake? Does anyone know of people who have experienced the same impairments and eventually they were able to restore those functions? What is the time frame for continued improvments in brain function? does it keep improving after 2 weeks of anstinence and aminos/supplements? Please advise.
