I've read a bit here and there in the google groups (archives) and nothing in there seems to hint anything about being drowsey or feeling 'kooky' in any way. I say kooky, because it isn't quite the drunk feeling - yet. But earlier today, went to the doc and that's what he gave me. Not allegra-D, but just the straight up allegra. Is there any reason I should be feeling like this? And is this normal at all? And nope, I'm not taking anything else - nor any kind of vitamins, supplements, etc.
