Problem is that there is no "one size fits all" cure. Plenty of things you can try but it is all trial and error. Personally I use Kwells. Plenty of blokes I know swear by the tablets ET flogs but they are very pricey and have to ordered in (didn't work for me). Pressure bands are another option as is a needle but it knocks you out for 24 hours or so. another tablet I have heard of working for some is Avil. It will depend on you too. I don't get crook on trailerboats and don't get crook on cruise ships but on a tug in anything over 20 knots after about 18 hours I am ready for a quick talk with Ralph. I don't even fight it anymore - just get it over and done with and then feel good again. Some come good after a few days but then there are some that never come good. Where you working and on what?
