You can make it!
You are being very responsible and doing what you can. You have notified your health care professionals (More than i can say for myself as I just chickened out of a T app!) I too take Klonopin until I feel numb. Then once I'm home I take a sleeping tab and hope that when I wake up in the morning I'll feel better. It's not ideal (I've been told i just don't face my emotions and sleep is my way of running away from everything) but until you see your pdoc, I guess this is the most responsible coping mechanism
I've fortunately never landed up in a place where I've hallucinated - please give me some insight if you are comfortable. When you feel it coming on and what the first subtle signs are.
Thinking of you!
