I think it's amazing for some and rubbish for others with not much in between.
But the only way you'll know is to try it and see.
After a bad experience with a GP doing it very unscientifically, I'd definitely recommend starting on one drug at a time, slowly going up in dose, starting at the lowest possible, and taking your time so you know what has caused what.
I came off 2700mg of gabapentin & 75ug of fentanyl, plus oramorph, and duloxitine, in the first badly managed experience. I felt SO much better after, turned out the symptoms that the GP keep increasing the dose for, were in fact side effects from the medicine itself (ffs)... The heart palpitations, pains in limbs, sweating, restless legs, confusion, brain fog & memory issues, depression and anxiety... Yup all the scary side effects. Particularly from the gabapentin & duloxitine, and it scared me off that family of drugs for a long time, so I had to keep taking lots of opiates instead which isn't good either.
Now I'm under a much more informed and sensible doc (GP & specialist), and so I'm trying Pregabalin (lyrica). But, I'm not scared about trying again, as this time is it being done in a completely different way. I am coming to the conclusion that there are no bad drugs, just bad (ill informed) HCPs!
So bearing in mind my previous experiences, I started on 25mg once a day, much lower than the normal starting dose but am being very cautious nowadays. Then 25mg x 2 a day, 50mg & 25mg, then 50 mg x2 a day. I stopped there for ages as the dry mouth and nose bleeds were not great, but slowly going up to 75mg as apparently, you can get side effects at one strength which don't occur at another strength. I think my mood might be suffering but it's hard to tell ... I plod onwards!
Apparently the loading dose is around 75 mg so I'm defo playing in the shallow end :)
I'd recommend keeping a diary so you can track pros and cons, as it can be very hard to look back & remember accurately especially if you're feeling very tired of fuzzy. Also asking anyone close to you if they notice any differences (+ or -) can be handy.
