So I have a trip to New York/ new jersey coming up for a funeral this weekend. Haven't flown for a while and my anxiety has been ramped up as I prepare for the trip. I usually use weed to deal with anxiety issues, but since I like my freedom, I can't travel with any. Because of this my doc gave me a klonopin prescription to use on the trip.

My questions are:
Should I expect to be drowsy? Should I take it at night if possible? Will I be able to take it and still function in NYC? Will I have withdrawal symptoms if I take it sparingly for 5-7 days?

Thanks for any replies.
