Suggest Treatment For Headache And Fatigue After Using Cerazette

Hi, I m 25 years old. i ve been on cerazette for the last 16 months. For quite a while now i have had irregular heavy periods, some lasting 4 weeks long. i m also experiencing headaches, tiredness and for 3 days this month i had numbness down one side of my face. I m currently working in asia so can t seek advice from my doctor in the UK. Could you give me some advice on what to do? What will happen if i stop taking pill and then start again? thankyou.
