That's wierd that your packet said to bring them with you to Montreal. Mine specifically said NOT to bring them.
Just as a note here, I just did my first shot of E after being off since March 9th, a little over 6 weeks ago, and have noticed no downsides. I really don't think being off of hormones for such a small time will really do anything unless you happen to have only been on HRT for a short period of time.
FYI - I stopped E and spiro 3 weeks before the surgery.
