I take pregabalin for fibro and other pain (50mg three times a day) - I'm not sure if the GPs are happy or not, but it was prescribed by two consultants, so they're overruled in any case
.
As I understand it, the deaths were mainly in people who were also using heroin and other illegal drugs, and it was the combination of heartrate-lowering drugs which caused the problems, and not just the pregabalin ifswim.
For me, I don't know if I'm addicted or not, if i miss a dose I'm in rather a lot of pain, so I'm pretty careful to take each dose. I don't feel any of the euphoria that's supposedly the main reason for taking it illegally (maybe my does isn't big enough for that?). I am mentally slower, but that's a combination of meds, fibro and pain, I've put on quite a bit of weight (but again, I don't always eat properly - due to fibro and pain -). Increasing/adding a dose makes me very sleepy for a couple of days till I get used to it, but I was increasing by 25mg at a time per dose.
Therapeutic dose for fibro according to the rheumatologist is 100mg 3 times a day, so I'm on half that, and am considering whether to go back to the GP and see if they'll increase my prescription.
There's a consultation regarding whether to make it a Class C drug or not (which may mean no repeats prescriptions, and having to go back to the GP every 28 days, which, if it's the case, will seriously piss me off - and presumably the GPs as well), but that does seem to be driven by the illegal use of pregabalin, and not those of us taking it as prescribed.
For me it's great, despite the weight gain, I really notice when the next dose is due (currently in 30 minutes, and my pain level is about a 4 I'd say). Can't help with coming off it, but I assume you'd do it very very slowly.
