Ack! Lol, I know it's not a crazy suggestion like you asked for, but (being an intuitive) I'll share this with you anyway:

If the timing is really that important to you then why not do something important and productive for yourself at that time?

This is what I'm to share with you...and the word "pledge" is important and not a word I ever use in this context, so it's just for you (I hope you understand the word choice, the reason for it, better than I)--

Make a pledge to yourself, about yourself, and for yourself (growth-wise), and then fulfill that pledge - not that you're lacking in these areas, but you will develop an even greater sense of personal integrity...gosh, I really feel like this could be such a joyous thing for you at results end.

Actually seek what it is you most want to find...heh, I somehow doubt that's downing a couple of shots of expensive hooch or running nekked through the park or jumping off a cliff with moth wings on. In other words: make it matter for your highest good.

Oh, and Happy Birthday fellow Scorpio... I'm on the 19th!
