Hey sweetie,
First of all, did you get my reply about the clonidine? I think you should give it a try. You never know
Second, everyone is different, however you will feel a bit worse tomorrow. How much worse? I can't answer that for you. The best thing to do is get out and keep your mind off "whats to come." The worst thing you can do is sit around and "wait" to see how you'll react.
Good luck my dear, and all the best
Sincerely,
emsmom
