The prob with taking extra anti-anxiety meds is they interfere with other anti-anxiety meds. Seredyn is a sedative it wil make u drowsy and lower you blood pressure it wil also increase the effects of anhy SSRI your taking and the sedative efect of alcohol, for these reasons i would consult your doctor if only so they can recommend a suitable dose.
I personally dont buy into Seredyn being non-habit forming as u have to taper off its usage when u cease taking it. I.e it has side effects wen u stop taking it.
Im thinking bout getting some seredyn to take when im really stressed just to supplement my citaelopram when needed. If i do I'l let kno if it works for me.
All the best
