... I've tried coffee, herbal coffee subsitute, walks in the fresh air, cocaine ... but I still feel drained. Anyone got any suggestions on how to beat this? Currently working 7 am til about 10pm writing up thesis. Can't think of any other way to get it done in time. So tired cant see computer screen properly ...

take a day off and sleep. you'll wake up refreshed. your mind and body just needs a break from the routine.

(1) Drink lots of water - dehydration makes you tired (2) look away from the computer screen every so often - look at something in the distance. This reduces eye strain/headaches/stress = tireness (3) Take regular breaks - don't wait until you can't do anymore -timetable a ten minute break every 1-2hours (4)Make sure you are sleeping well - a few hours quality sleep is better than a restless 8 hours - unwind before bed - write down anything that is playing on your mind and may keep you awake (5) you need physical exercise as well as mental exercise to help you sleep (6) avoid stimulants - this just produces a 'rollercoaster' that will drain you.

Hang on in there - it will soon be over!!! Book a holiday for when you have finished to avoid post PhD blues. Good luck

you need to get laid mate

yes...that could work too!!

How much time do you have left? Try to do something fun once a week.

Fee the same way. Hate the thesis, supervisors ... life!! Can't wait to be rid of the damm thing!

I would say take some time off. I know it sounds cliche but to relax and do something different for a few hours will hopefully mean you'll come back to your writing with a fresh perspective. Also if you're writing all the time it'll mean your mentally tired but not physically, confusing for your body. Why don't you take up some kind of sport? It would get you away from the computer and give you a different scene for an hour or two.

Maybe some "aggressive" music might help, I listen to black metal some time every day while writing....

well thanks for all the advice guys. Have reduced hours to quality 10 a day, and taking breaks and walks in between. Still hate thesis though and want to torture it slowly

How about eating it? Tasty with some garlic or drizzled in chocolate sauce?

Don't want to eat, want to stab

You need rooted REGGAE music to completely get over this. 'One thing about reggae music, when it hits you, you feel no pain' bob marley.

Take up martial arts. Maybe your body needs some intense exercise and som ebalance in your life. That's not so easy when you're wrting a thesis, however I've been there and you need balance or else you start going backwards instead of forwards.
