Just a word of caution.
Sometimes Anti-Depressants and Opiates combined can cause seizures in certain individuals.
Also certain Anti-Depressants and synthetic Opiates like Tramadol can cause Serotonin Syndrome. You DO NOT want SS.
Your mind will be flooded with Dopamine, Serotonin, Nor-Epinephrine - pleasure chemicals in the brain from taking a pleasure inducing drug like OXYCODONE - then the AD will act as a serotonin and dopamine re-uptake inhibitor.
Your brain goes nuts and you start having myoclonic uncontrolled muscle movements that then turn into a grand mal seizure in which you will probably swallow your tongue and die.
You need to understand people reporting restless leg syndrome on opiates? You know like nodding and having your muscles jerk, and twitch? That is because opiates, especially the synthetics derived from thebaine LOWER the seizure threshold quite a bit, putting anti-depressants into that mix can be bad news,
It depends on the person really, some will be fine, some will have problems.
There are a FEW combinations EVERYONE should probably avoid as it would be high risk no matter your personal history -
Like eating TRAMADOL and WELLBUTRIN by the handful. Also be very careful with MAOIs.
