Coffee and me

I try to stop my daily coffee 2 weeks ago. It ends up i got the withdrawal syndrome. Every day headache started 5.15 pm and above not relieve by sleeping. I thought it is post call syndrome due to lack of sleep initially but 2nd day, 3rd day post call still got same effect. I decided to drink back my coffee but the oral regurgitation and palpitation back in progress. I in biggest dilemma to drink or not to drink.
At last , i decided back to my coffee habit as I could not bear migraine.
Now i had no more palpitation and all side effect.
Maybe next time i should wear the above T shirt to stop coffee!
