Drug info - [SNRI] Common SNRI effects Compared to Tramadols' ?

[Swimster]

Firstly, yes, this is not the "SNRI" forum, although, there isn't one, so:

Swim heard that tramadol was a Rapidly-acting SNRI (Serotonin-Norepinephrine Re-uptake Inhibitor), but to anyone who is taking a common SNRI for depression: Can, or Does anyone compare Tramadol's "SNRI effects" to one of these common Antidepressant SNRI's:
venlafaxine-Effexor®,
desvenlafaxine- Pristiq®,
etc
- Pretty much the common SNRI's?

...Reason being is that swim has used Tramadol MANY times and love's its work, but swim might be put on Anti-Depressant's soon and swim is lazy and sluggish as it is now, and swim is thinking about the additional stimulation of an SNRI.

Does any swim compare the two?

Thanks
