Long term use of benzodiazepene's is generally not advised by doctors, it can have serious long and short term side effects and they are not easy to withdraw from, I've spoken with people who say being put on them long term was a bad thing for them and that the withdrawal from them was one of the hardest things they've ever had to endure. Of course some find them helpful, so it's not one size fits all. But as with everything moderation and responsibility is key.
A lot of people will have said that they won't get addicted as they don't have an addictive personality... that's rubbish in my opinion. Xanax is highly addictive in part due to the rapid nature of it's effect. You feel uncomfortable, you take a pill, you feel great because those feelings are awful- you've avoided those feelings. Your mind makes the connection. You've got a get out clause- never mind that you've heard or been told that it's an adjunct to the hard work that needs to be done too . So you start using it more often, but it's ok you haven't got an addictive personality, you'll be fine, you're better than all those other people that thought exactly the same thing and got hooked. And slowly it creeps up on you, it stops working as effectively so you need a higher dosage, you get put on a higher dosage but the same thing happens again, it takes more and more to get you to that comfortable place. And it's effects last about 5 hours before you need another one, then another one. You need a higher dosage to get the same effect as you used to so you go back to get that and your doctor says no... no more, that's the highest you can go. So you start to figue well if he's not going to give me the higher dosage I'll just double up occasionally when i need it. But only when i need it. Got to be smart about this. So you start doubling up, and then you need it again and before you know it you've run out and need a new prescription but you can't get it because the doctor knows it's too soon for you to have any more... unless you've not been taking them properly? 'Uh no i just lost a strip somewhere', crafty, but there's only so many times you can use that excuse. So maybe you start looking for other places to get it, although god knows what the quality will be like and if there'll actually be any of the drug you've asked for in what you get not to mention the financial or legal risk involved. Your tolerance to even basic discomfort has gone because you've been able to avoid it by taking the magic pill- but the discomfort lurks held barely held back by the drugs and it won't be stopped forever.
And add to this the withdrawals when you can't get the dose you need, the side effects, the fear, the uncertainty, the occasional thoughts of 'is this normal?' and then eventually either the forced or self chosen benzo withdrawal. And after that the need to face those original feelings you always had to face along with all the others added by addiction.
Nah you're not addicted. You're not the type...
Not that I speak from experience, not with xanax at any rate, although i've had some experience with other meds. and no, not everyone will get addicted to benzos. But they are known to be extremely addictive and a total bitch to come off of after long term use.
I'm staunchly in the medications as an adjunct to various supports or therapy field of thought, and that's from personal experience of relying only on medications. It's a sticking plaster, the original problems will always resurface if not dealt with at the root as far as possible- some people may always need medication in their lives and that's ok. But we can't just stick everyone on addictive medications, it's dangerous.
