Actually ive found the problem ,its called nausea .
I doubt that im the only one who had this problem ,  so i look around the web and ive found that quite numbers of creatine user experience it..

This is caused by few things
1) Mix creatine without enough water
2)Drink it way too fast
3)The creatine doesnt mix completely

So i correct it by mixing my creatine with more water , drink it slowly  take my time to finish the creatine and make sure all the creatine powder mix well enough with the water .

Now i feel much better consuming creatine .
For those who had same problem and those who are going to consume creatine in the future and encountered the same thing ,  you guys can try the solution above .
