Hi Breathless and welcome!
I am sorry to hear of this unexpected and confusing issue you are recently experiencing.
Along with the physical symptoms, are you also struggling with the anxiety management?
If so, it could just be that you are in need of an increase. You have some wiggle room, as some doctors are comfortable in prescribing up to 20 mg.
It seems too early for loss of efficacy/poop out...
...so talk to your doctor about
a possible bump up in your dosage when you consult with him/her.
I hope you get the answers you need soon.
Post with us anytime for anxiety support. We understand, care and support is key!
Check out our Resources at the top of the main forum page here as well. We have great self help material that if practiced regularly will make a big difference in how you feel.
Talk soon,
Scaredy Cat
