Need advice

Hey guys. I had a rough 3 years. Tried MDMA for the first time in my 30's. Didn't know much about side effects and supplements and stuff, you could say I was really reckless. Would take MDMA every months, going overboard and stuff. I'm now 3 months clean and I'm planning to go on. Recently I learned about supplement that can help the brain after use. Is it too late for me to start to take it now? I would read advices regarding taking supplement right after the rolling. So, what to do?
