Don't go on any dates during this period that involve drinking, even if it's just one drink at happy hour. You're just too impressionable and vulnerable at this time, and you'd be better off not going out at all, except with people you know and trust. The problem is, you're open to influences -- any influence that comes your way.
Your normal defense mechanisms just aren't in place, and neither are your boundaries. At the very least, anyone you date during this period will confuse you or make you feel uncomfortable. You'll have the sense that you don't exactly know what's going on; something is happening under the surface or behind the scenes. You won't be able to get a clear read on them or their intentions, even if you're ordinarily a very perceptive person. Part of the problem won't just be in your mind, either -- at this time you'll attract slippery types without meaning to. If that special someone seems evasive and hard to read, they might really be difficult to pin down. Either way, you'd be better off waiting a week or two to contact them or go out on a date. Until your head is clearer, you'll just have too much trouble keeping your wits about you.
