Hi Doctor! I Have Been Diagnosed With Graves Disease After

Hi doctor! I have been diagnosed with graves disease after a severe weight loss and other symptoms (hair fall, skin darkening, skin irritation) last year. Then been prescribed "neomarcazole 5" and "Inderal 10" like 4tablets of each per day. After 3months my levels thyroid are back to normal and the doctor reduced my dosages to 2tablets which means 1neomarcazole and 1Inderal twice a day.after few days with a symptom of uneasiness in the throat I voluntarily started talking my previous dosages as I was so petrified by my earlier(before medication) symptoms. I thought it was relapsing. But After few I have gained quite a few kilos. And now Got back to what the doctor suggested. But Still gaining weight. And there is an excessive amount of hair loss again. Should I stop taking the medicines now?
