Hello and welcome!
I'm definitely much more versed in Rx meds, but I know from being a part of this site for a long time that many people have had success using herbal remedies to help with their anxiety. I'm sure someone will come along and offer some ideas for you.
A question I would ask you is...is the Xanax working for you, and if so, why do you want to stop taking it in exchange for a non Rx med? Sometimes, the saying..."if it aint broke, don't fix it" applies REALLY well to these kinds of situations. Have you discussed any issues or concerns you have about this with your doctor? Have you tried therapy to help you cope with anxiety? If you want to make this change because you don't think you should reply on a prescription med, then you may want to rethink how the med is helping you and if it is something reasonable for your anxiety treatment. Try not to get caught up in what you think you "should" be doing...if how you're approaching your anxiety works, that should be good enough.
If you are interested in trying an herbal remedy, just remember that you must be tapered off of the Xanax under the supervision of your doctor. Also, don't equate the terms "natural" or "herbal" with "safe". The same considerations must be taken when starting any new medication, Rx or otherwise. There are adverse effects, contraindications, etc. I would recommend speaking with your doctor, pharmacist, or other professional who can help you make the decision that is best for you.
Best of luck! Keep in touch!
Be very aware that the 'alternative' remedies are often unvalidated by any .medical authority. Natural doesn't = healthy/safe/no side effects. Just think of Nightshade/Arsenic/Hemlock etc. Suggest you stick to what's been tried & tested & stands up to full scrutiny before you take any 'herbals etc'. Some give adverse reactions when taken with prescribed meds. Maybe someone on here will contradict me. OK if they provide proof!
I went to a local pharmacy like CVS and a pharmacist there told me chamomile tea. It helps ease anxiety.
"Natural" doesn't always mean safe, and come with their own side effects. You may want to post your question on the Alternative Medicines forum where there are some very knowledgable people on this.
