Hi OZ and welcome.
I am sorry to hear about
the rough time you have been having currently.:(
Do you work with a psychiatrist? Or is this your GP prescribing for you?
If you do not have a P-doc that you work with, I would suggest that it might be worth the time, effort and means to find one...as one could really help you with your Rx concerns...as well as truly understanding your PTSD.
Here is a link to our Resources. Inside you will find tons of self-help material that you may find useful during this time.

Here also is a good site for information of weaning off anxiety and A/D meds. It is not a substitute for your doctor's advice, but meant to be used alongside it.

Wishing you the best. Do keep us posted....and please consider starting your own new thread of introduction, so we can all welcome you. It is easy to go unnoticed at the end of these longer threads.
Talk to you soon,
S.C.
