Lenore,
Please talk to your doc before trying the herbal anti depressants. They too can interfer with the meds that are still in your system while you wean off one. And they *may* cause serious side effects. The best person to talk with is your pharmacist, actually. they have more information on this type of interaction than the docs do! LOL!
Also, even if you're not due to see your pdoc for awhile again, you should be able to talk to her/him on the phone, or at least leave a message and s/he get back to you. This is an important question with real consequences for your physical and mental health. You owe it to yourself to get all the information before imbarking on this type of change.
Wishing you well. Please let us know how it goes.
Shalom!
