Glad you made it back to the Sober Side, man!!
And I’ll just say it. This story had me addicted to its narrative flow. Mainly because I’ve been down that road (Detox/Fasting/Sweating/Exercising is what helped me break the addiction cycle).
Actually, I’ve heard of those studies using hallucinogens to break addiction and assist in mental illness. Never the Robitussin for that, however. Although, many of the inner city cats I know have been swallowing it for years as part of a homemade GET-HIGH Brew aka LEAN (containing various cough syrups n whatnot).
Thanks for this potent testimony. May U stay vigilant. Continued success.
