Tramadol is quite popular on other board I frequent.
Everyday use - forget it. Especially if you're after an anti-depressant effect. Your tolerance will build fairly quick and it's that point you'll either need to hop off the ride....or start messing with higher doses, which is never a smart thing with opiod acting drugs.
Couple of times a week, you can get away with that, but there are probably better long-term strategies.
Have you tried any of the older tricyclics or the MAOI's?. These tend to be far better drugs really than the SSRI's but docs are relucutant because their overodse margin is quite low and they carry a fair few interactions respectively.
I've had good success with the unique SSRE Tianeptine which I started last year.
Best of luck.
