Hey there. I'm a new user too, this is actually my first post, but I had an interesting experience with tramadol recently that I figured I should share...
I have a pretty high tolerance to opiates, I always have. I spent about a year and a half hooked on hydrocodone, eventually moved up to H, got clean after 9 months of suboxone, and finished that a few years ago. Recently, however, I came across some tramadol, and knowing how I could handle a lot in the past, I decided to take 400mg right off the bat (stupid, I know). About a half hour later, I was finishing up a cigarette outside the store, and that is the last thing I remember. Then, I woke up in the ground, surrounded by EMTs after experiencing a grand mal seizure. NEVER had anything like that before, not even close. I was blue from not breathing apparently. I spent a few hours in the hospital and got released, saying I shouldn't drive until I see a neurologist, blah blah blah, but obviously I knew it was from tramadol so I didn't worry about that. That was Thursday afternoon. Now it's almost 4 AM on Sunday morning, and my body is still incredibly sore from the seizure. I feel like I've been hit by a bus.
Long story short, be fucking careful with trams. I wouldn't take more than 4, MAYBE 5 50mg tabs if I were you. I don't ever want to experience that again, and I'm sure I'll feel the same after I get the medical bills...
