How my jet lag ends after 3months of Japan time.

After 3months of life in Japan. Flew back via San Francisco to Boston gave us a huge jet lag week. Usually 5days, but this time, I took around 10years to recover the jet lag.

In summer, there are so many fun stuffs to do in Boston. Outdoor exercise , outdoor painting, urban sketching outside, movies cruises, bicycling the coast etc..

I forced myself to keep awake in daytime with filling the fun things like above mentioned.

Despite all my efforts to keep me awake in daytime, I kept waking up 2am , 4am. So I did not set the alarm for the morning since I knew I will wake up and enjoy tired morning.
Suddenly the jet lag disappeared at the important appointment day! Woke up 9:30am.
Why today?

It was a Super bad timing to recover from my jet lag days.
I learned , even I can’t keep sleeping for some reason, I should set the alarm.
