Rubber band in my head

Im not sure if it was the new pillow or the fact that i slept without a blanket or lack of sleep or the nasi lemak and air jagung for breakfast that made me suffer a headache all day long. It felt like there was a big-ass rubber band in my head, squeezing my brain and trying to pop my eyes out. One of my friends suggested ginger ale to ease the wind ( i figured out that was the nuisance in my head). I picked up a small pack of Eno Halia.. bought some kuih from the cafe and head back to my room. I ate the snacks and downed the gingery spritey liquid and we were off to KLCC. One thing bothered me was that i'd pass gasses (or shud i say 'drop some bomb') in public. The last time i took some Eno I 'relieved' the winds like there was no tomorrow.. We went out by 3.40pm and i returned to my room at 10.40pm. (that's our typical outing.) Surprisingly, no sound came out of my butt hole.. mybe just a few burps but it was all good. Except that the headache did not go away! What happened to the ever-so-efficient Eno? Just a moment ago that the Eno kicked in and i was able to 'relieve' myself.. The headache is bearable now.. maybe sleeping will help loosen up the rubberband in my head.
