I have no sleeping difficulties, however, I am facing one in recent two week whereby I am having troubles sleeping.

I tried all different kind of methods to fall asleep such as l
1. Listening to music - Barely works because I am not used to using this method to sleep
2. Medidate to "calm" myself - Not working, brain keeps thinking
3. Go out for a walk - Initially i did go out for walk, but then since i didnt sleep well for weeks, i scared i pengsan and tend not to do such vigrous activities because i do feel pain in my heart
4. Keep counting 0-100 inside my brain - Not working

What natural methods do you guys do to make yourself go to sleep? Mind to share sifus? I cannot always rely on sleeping meds to make myself asleep man!
