I've done this many times, I've left the tramadol in cold turkey several times. I can tell you that it is not easy without medications to help, most likely venlafaxine is a bit gross the first few days, so you should use it on day 5 or 7 when the physical withdrawal phase ends. Pregabalin would help a lot in this stage, also in the physical part of the first days, you can use about 300mg per day until the week passes. After that you can increase it to 450mg or 600mg and add the venlafaxine, not much venlafaxine, a maximum of 150mg but you should start with the minimum dose. Tramadol withdrawal is a bitch. I am not taking tramadol now, I managed to take it in a certain way at the time I want without having withdrawal symptoms when I stop, I try to use it only 2 or 3 times a week at most. I was also in doses as high as you when I started to quit and had many relapses. But it is not impossible, in my case I always use benzos since I have been using them for 4 years anyway. Good luck amigo

, I know you can do it, I don't have a job either and I just left my parents' house, I'm living with a friend now, we both use drugs but we want to do things right this time
