Just because the cold medicine is on sale doesn't mean you should buy 2 boxes, one daytime, one nighttime. Especially if the boxes are extremely similar.
Yep, went to take some cold medicine the other night so I could sleep and breath through my nose but guess what? I accidentally took the daytime formula. It's been a long time since I've been that wired. It was like taking the best diet pills on the planet, all souped up with lots of ephedrine. Wow did I have some energy. I finally realized what I had done and drank a glass of wine, that brought me down a little. another glass and I was ready for bed.
I tell you this to prevent it from happening to you.
