These surface wipes sound good:

These sound good also. This page doesn't say anything about noro but the MediZar's own web page does, but didn't give an opportunity to buy them:

These actually sound better than Milton wipes; Milton's website has a page on Norovirus but I didn't find it that helpful. It was sort of weaseling out of saying most of its producs kill noro - implying they did but not really specifying it. Except their sterilising solution, of course - that DOES kill noro. the Milton hand gel is 'better' than most others at killing noro but not foolproof. I tend to go for Mentholatum Responsebeta.
Any sanitisers with 0.13% or more benzalkonium chloride should be fine, so don't worry about getting a really higher concentration - there's no need, and in fact it's quite a toxic substance in high concentrations so I doubt you'd find it.
I've bought Phenergan using the brand-name Phenergan at my local pharmacy, so it is out there. If you buy it online, use a reputable website with a pharmacy-registered logo with the green cross symbol. I think chemistdirect is fine like that so no problems. But Avomine and Sominex are the same stuff, work just the same. Avomine is slightly less drowsy I think but it is still promethazine, it's just in a different 'salt'. Don't get reliant on taking it too often, if you can help it, cos you don't need to, and it can make you really drowsy. I have cinnarizine (Stugeron) which I think is also pretty good, and far less drowsy-making

Don't take it often but have it there just in case, usually if I'm going on a long journey. Sorry for all the waffle xxx
