Hi Roxy and welcome back!
I don't have personal experience, but have heard many similar feelings expressed from members who are trying a new Rx for the first time and have concerns.
While there can be some unpleasant start up effects for some people, not everyone experiences them. Also they are temporary and often end up being a small price to pay for a medication that after a few weeks, can give you years of benefits.
This is of course a personal decision, but consider your quality of life with anxiety. Is the possibility of some side effects more uncomfortable than the other option of living with the anxiety as is? Of course only you can answer this, and I am not trying to sway your decision...just giving you something to think about
.
I wish you the best with your decision...keep us posted so we can keep you in support!
S.C.
