No problem.. sleep when ever you feel like... If you try to sleep early by 9:30 then you will be able to.. have early dinner and then little walk n sleep... Avoid watching tv at night.. chant mantras... Actually if you wake up at 1 then you miss you important meals... Get up by 8 maximum then bath and take food and sleep if you feel like.. <br> But try to maintain early bed time.. it will be good .
