Guess the composition of what you call Sudafed must be fundamentally different to what we do, because you can walk into any chemist or supermarket and pick up a 100ml (3.5floz)bottle for around £4 (which, at the rate the pound is falling, is probably around $4 now). The time-release decongestant caps are a bit more.
Does the US version still contain ephedrine (as opposed to pseudoephedrine as ours does)…? From my, albeit extremely limited, chemical knowledge, I had thought that there wasn’t all that much difference between the two chemically (and our government has a penchant for banning things for absolutely no reason other than they’re ‘bad’ – but, obviously, alcohol isn’t bad – and neither was coke when the conk it was being snorted up was attached to the former chancellor). Or is what you call Sudafed and what I do two completely different things…?
