Unfortunately a lot of drugs end up in dependency. Pregabalin is used in many different setting, not just psychiatric.
I too worked in addictions and many different drugs get abused. It's not only the effect of the drugs but also the availability.
For many who end up taking pregablin it is often a last resort. As rightly pointed out, it's no longer a drug that is readily prescribed due to its propensity for abuse.
That being said, many, myself included end up on drugs like these because they are out of options. A life of constant fear is not a good one, especially when your feelings impact others like your children.
I don't imagine many people end up on this drug, that is difficult to get in the first place without exhausting all other options first.
I do believe counseling, cbt etc have their place but equally does medication. Unless you have experienced the true fear that comes with extreme anxiety you have no idea.
It's important to educate yourself on all aspects of a medication you are taking. It's not helpful however to give an unbalanced view, only pointing out the negatives.
Like all drugs, there are pros and cons. To me it has given me my life back and given me a future. Everything else had been tried. Every single thing that most people take for granted like nipping to the shops, meeting friends for coffee, being employed, outings with their kids had been taken from me.
I went from someone with a professional job who dealt with multi disciplinary teams, clients, families all day to a very very small life of staying at home literally fearing the doorbell.
