It already happened twice but this time the effect was so obvious and it’s evident. I could really felt it within my veins. Last time I had java chip frapp I slept very late but well, I guess that’s just because of the common effects of coffee(caffeine).
Normally I’m not hit by those kinds of things when drinking coffee. Anways, the other day I drunk java chip frapp and after an hour maybe I can feel my heart palpitated. I’m kinda getting so nervous and/or excited for no reasons at all. It didn’t just lasted for an hour but for HOURS. But not only that ‘coz this time I can’t really sleep even though I went to bed on my usual sleeping hour, yeah I know I have trouble sleeping since the year started but last night was a different story. I kept tossing and rolling over the bed for around 5 hours??? Imagine the time I’ve wasted!
On the other hand, it is clear that coffee is not for everyone. In excessive amounts – meaning more than whatever an individual’s body can tolerate – coffee can cause nervousness, jitters, and rapid heartbeat. – http://www.healingdaily.com/detoxification-diet/coffee.htm
I got 2 java chip here 
. One from starbucks and one from seattles. Btw, Last time It happened I had frap from startbucks and yesterday from seattles. Don’t you think seattles’ java chip frapp has more side effects on me? But really both tasted sooooooo good
