Hmmm...I just read your profile, and it says that your hobby is
"reading."
Well, just make sure your posture is good when you read. I hope you
dun read while lying on the bed or sofa, or in an awkward position.
Also, dun read for too long without a break (walk around, stretch a
bit, drink some fruit juice, etc.)
There were some interesting suggestions here like hot showers and
baths, which are nice things to do (which I might try myself next
time!), but in my humble opinion, I believe that the "meat" or the
"bread and butter" of improving yourself, is to improve your health
overall.
Improving overall health = proper exercise (weightlifiting - dun
worry, females won't become like Arnold, unless u take drugs or
something), food/water (alot!!!! eat/drink often!!!!), and
sleep.
My guess is that you're feeling tired all the time, right? Very
lethargic and sleepy, even though you have a lot of sleep, right?
Maybe headaches, too?
I used to be like that.... I always had headaches and felt
lethargic - I wondered if I was cursed, or something like that. But
truth be told, it was because of my lifestyle: sleep late, wake up
late, NEVER exercise, skip breakfast (cause I wake up late, lah!),
do computer too much, don't eat regularly, etc. etc. etc.
Once I changed that, nearly all my ailments and pain *miraculously*
disappeared. Haha, actually, there's no miracle or magic pill....
it's just simple health sense....and discipline. Yeah, it was
really hard to change my lifestyle at first, and it's still a
struggle occasionally, but it gets easier as time goes by.
Good luck!
