Small frequent meals so the stomach acid has something to churn on other than itself - up to every hour, and as little as a couple of crackers.
Paihia Bombers - magic sea sickness preventative. Combination antihistamine, caffeine to combat drowsiness, and an anti nausea additive. They seem to be far superior to Sea Legs and other tablet remedies. I have used them on offshore liveaboards in the Coral Sea and to Three Kings. I have buddies who are far more prone to sea sickness than me who use them on every boat trip, but still survived the Coral Sea journey without sickness. I recommend taking them for a day on shore first, and trying them on a familiar dive first before using them on a liveaboard in extreme conditions, and there are also medical questions which the place selling them asks to see if you are a suitable candidate for them. PM me for details on how to get them.
Not sure how that helps you in Oz sorry Vampire, but maybe next time you are over diving at the Knights...
I was told by some Military Doc's to steer well clear of anti-histamines and diving period...weird..
Sfish did some research into this and according also to DAN anti-histamines are also a no-no.
As I understand it, (and I am no medical expert) a reason antihistermines are not recommended for divers is because taking them can make you drowsy. Although you're unlikely to fall asleep while diving (though I have come close on a night dive once...seriously...I was that relaxed), I suppose they do have the ability to impair judgement and therefore your ability to make the 'right' decision at the moment you may need to during the dive. Note that Pahia Bombers include caffine to help combat the drowsiness. I would, however, guess their affect (like all of the sea sickness medication we have mentioned) differs in each of us, so, as Scuba Sam says, I would see how they affect you on land first. If they make you feel drowsy and you would be unhappy diving in that state, then don't dive. If you find the caffine kick sufficient to overcome the drowsiness, then consider getting wet. At the end of the day it's up to you.

1. Will antihistamines make me more susceptible to DCI? Older sedating antihistamines could exaggerate the effect of nitrogen narcosis in a diver. There is no obvious physiological effect of their action that would make DCI more likely. Poor decision making as a result of impaired cognition however clearly can lead to an accident.
2. Will diving make any side effects of antihistamines worse? Other than potentially exacerbating nitrogen narcosis, no.
3. Will my exercise tolerance or thought processes be affected by use of antihistamines? If using a non sedating antihistamine, probably not.
Personally, I only take ginger which I have had mixed success with. I don't tend to get sea sick too often (thank goodness!) and so have every sympathy for those who do.
