I have been on amoxycillin since Weds, for a recurring tooth problem. Almost immediately I developed galloping diarrhoea - not as bad as when you are actually ill but I am needing the loo several times a day. I am going out on Thurs - will take the last antibiotic in the morning - and really don't want to have to go to the loo when I am out. Am wondering whether to take an Immodium tablet on Weds night. I don't normally need anything like that - just would appreciate your thoughts.
