dude! i think u're allergic to certain proteins in seafood. some of my friends are like that as well. they'll swell up & itchy on various parts of the body & to extreme extend fall sick badly. be careful.
over here at my place (which is a swamp!) mud crabs can be caught provided u follow the tides & the habits of the crabs. they're much much nicer than sea crabs, don't u think, mea?
for moslems, all alcohol isn't halal & that means beer, wine, whisky, etc... . heck, even the chinese white wine used for cooking isn't halal. the same goes for alcohol-based perfume & stuff.
& thanks for the warm 'welcome back'. nice to be back among online friends. & u should be taking vacations. malaysia's relatively cheap & has a lot to offer for great holidays. just let me know what u look forward to for your vacation if u ever consider malaysia & i can give some recommendations. bring the other aussies as well, like handefood.
