Ihave been hiccupping for two days and I would like tossp

Breath in and hold your breath for about ten seconds, then breathe out slowly. Repeat three or four times. Then do it again twenty minutes later.
Breathe into a paper bag (do not cover your head with the bag)
Bring your knees to your chest and hug them for a couple of minutes
Gargle with iced water
Drink from the far side of the glass - stand up, bend over and put your mouth on the opposite side of the glass. As you bend, tilt the glass away from you and drink
Gently compress your chest, this can be achieved by leaning forward
Place a couple of drops of vinegar in your mouth
Place gentle pressure on your nose while you swallow
Place granulated sugar in your mouth. When it melts, swallow it
Press your diaphragm gently
Sip very cold water slowly
Drink a glass of warm water very slowly, all the way down without breathing
Take a thin slice of lemon, place it on your tongue and suck it like a sweet
Burping - some people find that if they consume a fizzy drink and burp, their hiccups go away. However, some doctors warn that sodas may trigger hiccups.
Waiting - in the vast majority of cases, hiccups go away on their own. Some say that by simply waiting and not worrying about them, the problem is likely to resolve more quickly
Pull your tongue - hold the end of your tongue with your fingers and tug. This stimulates the vagus nerve and eases diaphragm spasms, which may sometimes stop hiccups (this often does not work)

I've also heard that smoking a single cigarette can help. I'm a smoker, it doesn't work for me, but from a number of non-smokers I know, they'll swear by it.

It is not unhealthy to smoke one cigarette a year by the way for all those haters. Please don't try this if you're under 18 or have strong morals against smoking. Please don't take up smoking, it does not prevent hiccups. Smoking is highly addictive and may result in light-headedness. Proceed with caution. Consult a physician if you have any doubts about by cautions, they may agree or disagree.

Infojunkie, it may not be harmful to smoke one cigarette a year, but depending on the age of the poster, which we don't know, it could be illegal.
