Hi lins, welcome back....
I probably am not the best person to be trying to answer your question, but I can attempt anyway...
I personally have never had the luxury of xanax or anything else like while in wds...but I have heard alot of people say that yes, it does help. With what, I can only assume, I would imagine it would help you sleep, and possible cut down on some of the restless, legs/arms/body...etc,, not sure...but hopefully someone else will come along with a better answer for you...
Just know, that nothing, at least in my experience, except more pills will take away the withdrawl completely, and quitting will be not be any easer tomorrow or next week, than it is right now...so just know there will be discomfort, maybe more than you think you can handle at times, but there is another side to this addiction mess we all find ourselves in. I have not quite made it all the way yet, but I do have 18 days behind me, and beleive me, if I can do this, anyone can!!!!!! Stay strong...do the right thing.....JUST DO IT

You will be so much happier for it!!!
If you need help or just to talk, just let me know!!!
