Seriously, has anyone ever taken 12-hour Sudafed without knowing that it was a stimulant? It's one of the drugs you have to buy from the pharmacist because people use it to make meth--which is surprising as the last thing I would have thought anyone would want to do was to INTENSIFY the feeling of just plain old Sudafed. So, being a foolish person who tends to believe that over the counter drugs are relatively harmless, I took Sudafed for 48-hours before I finally went to the doctor for something less scary for allergies. It's not quite as silly as it sounds--the first night I couldn't sleep, I assumed it was just because I had taken Nyquil for 3 nights in a row before that, and that usually would make it hard for me to sleep the next night. But the following night when I was exhausted but ready to repaint the bedroom at 3:00 AM, I did figure things out, and have stashed away the rest of the scary Sudafed until maybe a future Christmas where I am stupid enough...
