Ginger and honey ... 
- get a large piece of fresh raw ginger - preferably organic (any root that grows in the ground probably is better if it's organic). - use a grater to grate a peeled hunk into a large mug. - add a large tablespoon or more of honey. If you can get it, try and get raw honey. Even better - but expensive - is New Zealand Manuka honey.
http://en.wikipedia.org/wiki/Leptospermum_scoparium - get some lemons - the ugly organically grown ones are better as you want to use the peel as well; use them two ways: 1) use a grater to get the yellow rind (zest) but not the bitter pith. 2) Then cut off a quarter, half or squeeze the juice into your mug. - top up with hot water; let it steep for a minute or two and drink. - drink as often as you need; if you can take it - eat the remaining ginger with a small spoon. - you might be tempted to add booze to make a toddy. Don't. Contrary to popular belief, the research seems to strongly indicate that alcohol is not conducive to recovery. or, do it spartan-style and break of a nice sized chunk of raw ginger (cleaned & peeled), pop in your mouth, chew & swallow. I don't think the ginger in the tubes is as effective. Raw ginger is readily available anyways, so there is no excuse for not getting the real thing. --
