Pcos, Harmonal imbalance-Irregular

Hi Sir/Madam, I am writing this for myself, I have irregular period problem from the day when I first got periods.. I used to get periods for 2-3 months.. with time it is getting even worse. I consulted gynaecologist she said I have pcos and harmones imbalance gave 24 days cyclic tablets which helped me to get periods regularly but I used to bleed very less while using those tablets , I continued using them for 4 months. After stoping them again they became irregular. I know pcos need change in lifestyle. But I'm a software employee I go to office at 10AM and reach hostel at 9:30PM. I'm soo worried about my condition feeling depressed sometimes I'm putting on weight, will there be any permanent cure for my irregular periods and pcos problem. I am going to get married next year will this become a problem ? Pls suggest something needful. I stay in Hyderabad.
