Tramadol nightmares

[beena]

SWIM has been taking and addicted to Tramadol (amongst other things) for about two years. She has suffered from various withdrawal symptoms when she has tried to stop use. Recently though a new element has arisen to the withdrawal symptoms she suffers from....if she hasn't taken the dose she needs to take before going to bed at night when she falls asleep she starts to have nightmares. They're not like normal nightmares though - SWIM is very aware that she is sleeping and that she's having a nightmare....she tries to wake herself up and she can actually sense that her body is paralysed cos she is asleep. It is a really horrible and quite frightening experience that is quite difficult to describe too.
SWIM's boyfriend has watched her whilst she was having one of these experiences (he shook her to wake her up when he realised something was wrong). He said that her eyes were flickering very fast (her eyes going to the back of her head) and that she started making choking noises. SWIM thinks the noises was her straining herself to try and wake up.
Other times SWIM has screamed aloud and woken herself up with the noise. If SWIM just goes back to sleep (without getting up and actually taking the tramadol first) the nightmares start again....and this will happen until SWIM does get up and take the tramadol - that is how she can be so certain that it is tramadol withdrawals that is causing this to happen.
SWIM has to get up in the middle of the night, take tramadol and then sit up and wait at least 30 minutes for them to kick in before she can go to sleep again.
SWIM was just wondering if anyone else suffers with these kind of withdrawals or has even heard of anything like it before?
SWIM is addicted to other drugs too, such as crack-cocaine, morphine (MST) and heroin and she has never experienced anything like this from those drugs, which SWIM would consider far worse addictions....it's very strange...SWIM hates it.
