Speeding through the night

Sudafed, and its active ingredient pseudoephedrine, are clearly not for me: I took one last night and had a terrible reaction to it.

Side effects for pseudoephedrine, according to Medline:

• nervousness
• restlessness
• dizziness
• difficulty sleeping
• upset stomach

Yes, yes, no, yes, no. A very odd feeling: although I was physically tired, my mind was racing so fast that I couldn't get to sleep.

Says Wikipedia:

As with other phenylethylamines, [pseudoephedrine] is very chemically similar to amphetamines.

No kidding; I certainly felt like I was speeding. While the decongestant effect worked very well, the side effects rule this one out for me from now on.
