Gynaec problem. Don't work. plshelp.

All my life i have suffered during periods. I have very heavy and painful periods during which i have severe pain and also vomiting, so much so, that the vomiting is sometimes non stop. The pain is so much that i avoided school, college and now work. The pain gets too much and sometimes i get home back from work. The pain is particularly worse on 2nd & 4th days. My bowel movements become frequent .I'm also very sensitive to smells and i vomi at the slightest odor. I've been consulting gynaecologists ever since i was 13 and have been prescribed oral contraceptives thrice for 6 months each, but the condition gets back to same after stopping medicine. My ultra sound apparently revealed polycystic ovary disease. This has become a life long routine. I cannot go anywhere without worrying about cramps and vomiting. I'm 29 now and it causes embarrassment at work as well (as i vomit a lot).I do take anti gastritis medicine and Cyclopam/MeftalSpas, but most of the times they don't work. plshelp.
