The first time I took Tramadol sucked. I didn't know anything about it and I thought they were like taking Oxy. After taking a few with some hydrocodone, I vomited and felt like shit. Couldn't sleep. Finally did research on here and learned it should be dosed differently. Start with 50 mgs, then take another every 30 - 60 minutes, up until your tolerance allows. This eliminated the vomiting. I started developing a tolerance pretty quickly though. What used to give me a good buzz and tons of energy all day was only 300-500mgs. Then I started upping it and risking seizures. I'm now up to 900-1100mgs per day, just once per week and it's not even close to what I used to feel. I take klonopin each time to reduce the risk of seizures, but I've been extreme lucky to have never experienced one (knock on wood). But I always have a Tramadol Hangover the next day though. Tramadol is something I take because it's easy and cheap to obtain ... And I can resist taking it everyday. If I have Oxycodone, I have no self-restraint and take it everyday until it's gone. I am currently trying to take a hiatus from Tramadol to reduce my tolerance. So far, today is day 9, which is the longest I've gone in a year.
