Shit that sounds pretty good. I might try it. I wonder though, how does it compare to something like Prozac? That's the shit I take on a daily basis and I'm still depressed as fuck when I'm not high.
Good God Almighty please don't start mucking around with tramadol except for its established use as a poorly-effective opioid pain medication, and then only under the supervision of a bona fide medical doctor. Back in the days when you could order tramadol by the bucketload online I took tons of the stuff for recreational purposes. Wasn't great for fun times but it was relatively cheap and getting caught with a thousand of them wouldn't get you in any legal trouble. I had lots of problems then and one of them was severe depression. Whether taking a little or a lot tramadol did nothing for my depression. And the skanky shit damn near killed me. I posted a comment earlier about my experiences with tramadol but here's TL/DR version: it gave me a grand mal seizure when I was at home by myself, right after I'd finished a huge meal. And when I went down it was flat on my back. Lots of people vomit during seizures. It's common. And with my stomach full of food and not being conscious to keep my airway clear, had I just gone that one step further and puked my wife would have found be blue and dead as Abraham Lincoln when she got home from her night shift in the morning. It was pure serendipity that it didn't kill me. I had several other friends who were fools like me and they too took tons of tramadol and every last one of them had at least one grand mal seizure of their own, one of them behind the wheel of a car on the interstate. He spent months in the hospital and has never regained the ability to walk normally but hey, at least he didn't become an organ donor. The list of drugs and substances that, mixed with tramadol, drastically lower the seizure threshold is long as hell. Including pretty much every single serotonergic antidepressant (e.g. SSRIs) on the planet. Tramadol is shit for pain. It's shit for recreational purposes. It will either have no effect on your depression or it will make it worse. And it might just give you a seizure and kill you. Please oh please don't experiment with the stuff.
You say you're on Prozac. If you mix it or ANY SSRI with tramadol you *will* have a grand mal seizure. It's just a question of when. In my case it was using Paxil at the same time I was taking loads of tramadol that nearly put me in the ground.
I do note that at least in the USA it's now a schedule 3 controlled dangerous substance so it's as hard to get as other narcotics like codiene and hydrocodone. The likelihood of your finding a cheap source that won't just scam you or cause you to go to jail is slim. So you're probably okay even if you still want to fool around with the stuff. One of the extremely rare times I actually agree with a drug prohibition law. If you're outside of the USA and can easily get your hands on the stuff, and you're foolish enough to play with it, well at least let your relatives know so they can get a jump start on picking out a cheap dark suit for you for your funeral.
If you want to try an opioid for depression I recommend you try either 7-hydroxymitragynine or tianeptine sodium. Tianeptine is shit and kind of hard to find at a reasonable price these days but it is an opioid that IS also a legal prescription antidepressant in Europe (called Stabilon) and for recreational purposes is sort of okay. But it habituates quickly and after a month or two of frequent use becomes more or less useless. 7-hydroxymitragynine (7OH) is cheaper, much more effective, more fun if you're into recreational opioid use, and still relatively cheap if you buy it online from the right sources, and AVOID buying it from smoke shops/head shops. Both substances are illegal in some states but are still fully legal in most and under US federal law as well. Either would be a vastly better choice to experiment with than Tramadol. I've been using 7OH daily for a couple of years now for both chronic pain (I used it to get through a hip replacement and it was a godsend) and depression and surprisingly it still works well. Just at a much higher dosage than before. But that's the case with all opioids with chronic use. They habituate.
Good luck.
Edit: for me at least 7OH is a much more useful opioid than buprenorphine ever was. Taken infrequently bupe can give a so-so buzz. But for me at least the only use I'd ever have for it would be its intended use of trying to get off of opioids altogether. If you take it the way it's intended after a few days to a week you will feel no buzz, nothing, from it and it's a powerful antagonist and will also keep you from getting off on any other opioid as well. Fifty milligrams of 7OH feels much nicer than any dosage of buprenorphine and doesn't carry with it all the attendant risks--like pain medication being totally useless for you until the bupe is completely out of your system, a huge problem if you get hurt or need emergency surgery while taking the stuff. Compared to buprenorphine, 7OH is also dirt cheap and easy and legal to get. But that's my experience. Your mileage may vary.
