Whats everyones hangover cures?

These days my hangovers are so bad theyre like a comedown and make me feel mentally shagged and completly spaced out, usually boardering insane

All I ever do is eat some cereal, and wait it out.

Anyone tried them RU21 type pill things? Would they help my wierd nasty mental hangovers (I don't really get any pyshicall hangover problems).
