Detoxing heavy Aspartame?

I've been a heavy user of Aspartame in the last year. Multiple doses per day.

I've been stuttering, forgetful in my words and actions, feeling spacey, been having teeth issues, I have a constant burning feeling on my tongue and roof of mouth, and very irritable/angry.

I wasn't this way before I began the Aspartame product (which I wasn't aware that Aspartame was one of the main ingredients until about 6 months in).

Is anyone savvy on how to detox aspartame from the system and repair the damages done to the brain? (And getting rid of this burning sensation in my mouth would be great, too!)

Thank you.
