Hi I gave up smoking 11 months ago, and since then I find that I have not been going toilet regularly, I am 62 years old and people say that it happens when you get older. My doctor has given me senna tablets and that works, she has given me it on priscription so that I can take it every day, when I try to stop taking it I dont go again and I get horrible back pains. I do keep fit four times a week and zumba one time a week, I eat lots of vegetables, and I have started eating prunes but nothing helps naturally, I am worried that taking the senna tablets will muck up my normal system and I would not be able to come off of them. Can you tell me if it is alright to take these tablets every day. Thank you
