I HAVE IBS HELP ME?

Why in the world are you taking laxatives?  Constipation is not the same as having IBS.  IBS has a lot of other more prominent symptoms.  You need to see a gastroenterologist for a proper medical evaluation and treatment (if necessary).  Self diagnosing and self medicating are never proper treatments for IBS or any other intestinal disorder.

Have you told your regular doctor?

If your doctor has diagnosed you with IBS- C, then he should have had some treatment regimen for you.

YOu need professional help. 

It sounds like you have constipation rather than IBS (which is more likely to cause diarrhea). You need to add exercise, fiber and more water to your diet. Avoid foods that can cause constipation such as cheese, chocolate, sugar and sugary desserts or sugary drinks. Eat berries, fresh fruit other than bananas, nuts, beans, whole grains and lots of vegetables. Have some corn on the cob while it is in season. Eat a green salad (including romaine, spinach or other dark leafy greens) with supper every night. Stay away from processed foods such as sugary breakfast foods, hot dogs, pizza or McDonalds for any meal. Go for a walk every day -- just 20 minutes a day can make a big difference. A longer walk is even better -- 40-45 minutes. You need to wake up your digestive system so it can eliminate on its own instead of requiring laxatives.
