hya embarrrassed...thanks for your advice***.... the only advice i can give u about heading abroad is do what i did on holiday.: walk into a little "friendly chemist"! and buy a pack of laxitives.... twas funny actually whan i was buyiny them away,.. the assistant couldnt speak english so i had to grip my stomach and do actions like it was all notted up.. they were sooooooooooo helpfull and professional about it like a doctor r somthing.. it was the best move ever. i took one in the evening and about a day r 2 later i felt grrreeeeat.. they really r great for a trip away and soooo predictable as i was terrified of getting the runs but no they really do work.... guud luck and go go go******
