I agree with Koala.

A taper would be much more comfortable. Tramadol has some SSRI effects also, and sudden withdrawal of that family of drugs affect serotonin receptors too.

Here is a website to read:

This withdrawal depends on how much you take a day, and for how long you took it and if it was regularly daily.
Many of the symptoms reflect the mu receptors, and are similar to opiate withdrawal.

I find this drug puzzling myself. I can't tolerate it very well, so only use 1/2 tablet for severe pain days. I don't take it everyday. A whole tablet made me "zoom" all night! The weirdest thing like hallucinations, but not quite.

I think people react to it differently. Some people become very habituated to it, and others don't. I don't understand why it is not a controlled substance.
