My name is abhishek and age is 22. i was a cigarette addict and i used to chew tobacco till few days ago, but i have recently dropped these to 2-3 cigarettes per day. I am having regular headaches in left part or right part, but not both together. I also wear glasses, -2 power, and study under table lamp for over 12 hours (preparing for Civil Services). I also regularly and often heavily consume caffeine (nescafe coffee powder + boiling water, no sugar or milk), and i'm trying to cut it down too, since these dont keep me awake anymore (resistant I've become, i think).. what should i do, i try to avoid medicines.. please suggest the cure, i haven't time for a doctor ... and it's 4am in the morning and i'm sleepy... thanks a lot :)
