Hey,you have altered sleep cycle ,go to bed and get at right time ,don't sleep in day time ,avoid coffee ,tea in night ,don't watch TV ,computer while sleeping , do exercise daily in morning , don't worry too much ,don't strain yourself much...Avoid large meals and beverages before bed. A light snack is fine. But avoid eating too much late in the evening to reduce the chance of gastroesophageal reflux disease (GERD) and improve sleep. Drink less before bedtime so that you won't have to urinate as often....stop using ear plugs and Consult physician they will do the needful.
