I have quit using cocaine after 2 years of use 10 days ago when I first noticed memory, concentration, and analytical impairments while performing work functions on the job. It was frustrating as my attention span became noticing impaired and I had to write down information from emails or assignments on a memo pad because of impairments in attention span and concentration. In response to the panic, I started taking cdp choline and ginkgo to boost memory and concentration levels. Thus far I haven't seen any improvements until an hour ago when I opened some files from work and was able to somewhat decipher and analyze the material. Slight cognitive improvement but not there fully. In addition to the memory boosters, I have been taking dlpa, 5htp, and l tyrosine to increase depleted dopamine and serotonin levels. I don't know if it's placebo effect but today is the first time since I've felt stress and depression free since Ive noticed the impairments. I would like to know if the combination of supplements I'm taking is safe and whether prolonged abstinence and exercise can help the brain reverse these impairments. Is there nutrients, supplements, or proven medical treatment that can help quicken the recovery of these impairments? I hope the damage is not permanent. Please advise!
