My advice: green or black tea (hot preferably, and not
too strong... relaxing if done nicely - green tea should be prepared like any other herb tea, avoid boiling water because it destroys the "good stuff"), mild sedative herbs like catnip, lemon balm, mint, chamomile, and so on (tea made with hot (NOT BOILING!) or fresh herbs eaten raw). Magnesium supplementation may help too.
Valerian root can be an OK sedative/anxiolytic too.
Hot showers and baths can do a lot for relaxing the body and mind - especially if you have some mineral bath salts to add to your soak. (not the fucking "bath salts" that are stimulanting - I mean Epsom salts). Mangesium is actually absorbed transdermally so just dump a few tablespoons of epsom salts (magnesium sulpahet) into your bath and have a good soak. You'll com out loose and limber and hopefully quite relaxed.
Try to get the right balance of sleep and activity. Physical excercise may help a lot if you are primarily chairbound most of your day.
If you eat a lot of junk food, or eat poorly (less/more often than you should, or lack of vegetables and fruits), dietary adjustments can help. Also be sure to take vitamin supplements, doubly so if you are a vegitarian/vegan.
I have heard rumours that buspirone (5-HT1a partial agonist among others) is sometimes Rx for General Anxiety Disorder. The literature reports it's fairly effective but I have hard everal people tell me it's shitty. But docs also rx are things like hydroxyzine that are essentlally just sedative-hypnotics for anxiety, so take that with a grain of salt. Corollary: try diphenhydramine or promethazine.
Kava Kava is a GABAergic like a mild version of alcohol/benzos - it would form dependency but nowhere as severe as benzos do.
GABA itself has only mild peripheral effects, but it's worth a try to see if it works for you. Picamilon & other true prodrugs may be more effective.
Ashwaganda has been found to be
just as effective as lorazepam in rats - that may help too.
Another more obvious way to repair your problem is discoover what your stressors are and work to confront them.
Whatever you do stay off the benzos
