I have always had irregular bowel movements I.e. Every three days is quite normal for me. I try to drink 1.5 litres of water a day and run three times a week. Every once in a while I will go through A period of a week when I don't go properly at all . I am thinking of taking some sort of laxative / stool softener to get things moving . What would you recommend ? am gong on holiday in 5 days and want to try and resolve before I go. Thanks ,
