Sudafed
Worth noting - there are 2 things marketed as Sudafed in the UK, and they're different.

The kind on the open shelves is Phenylephrine, which is pretty good as placebos go for your stuffed up nose, but probably no damned use for this.

The other kind is Pseudoephedrine, which for the very reason of this recipe, is kept behind the counter and you have to ask the pharmacist for. And they don't let you buy it in large quantities.

Finally, what not a lot of people know is that this family of stimulants is actually the basis for Ritalin. Yes, Ritalin is a stimulant. It controls the behaviour of ADHD patients by stimulating the areas of the brain used for conscious control of random urges (that voice that tells you "Hmmm - that would be A Bad Idea" and "Concentrating on what you're trying to get done might be handy"), which the rest of the population have operating reasonably well. So if you have difficulty focusing on getting shit finished, self-medication with Sudafed might not be an unreasonable response.

IANAD, YMMV, AYOR, This Is Not Advice etc
