Amphetamines are still prescribed by GP's - i did a prescription for some the other day. For narcolepsy!!
Try hot lemon and honey with a smidge of whisky in. Goes down a treat and works wonders for a cold. People in the UK - if you start to feel a cold coming on try Vicks First defence nasal spray* ITS FANTASTIC - i felt horrid at work and this stops a cold in its tracks!!
*always read the label!!
