Working Time Difficulties

I'm really having a hard time with my time for doing my online work. In the past it's easy to finish everything for just an hour or two but now that paid blogging is picking up again the work is taking its toll on my health. For the past three weeks I've spent three overnights just to cope up with my online tasks and slowly my body is giving up on spending too much hours working late nights and early dawn. 

Sometimes I go to my office work with just an hour of sleep which I can carry well but deep inside I know it will affect my health. As I'm in my 40s already I know that I should take everything in moderation including sleeping late because it not like when I was younger. Often I thought of my healthy meal diet and shrugged it off as not effective if I overworked myself every night. A healthy diet plan will only work with regular exercise and complete hours of sleep so I'd better plan this out or I'll be obese sooner than I expected.
