does anyone here drink Celsius energy drink?

Question

Have you ever had any side effects from it? 
I drink only a half a can before I work out, as it's a pre-workout drink that's supposed to help you burn a lot more calories and body fat....
Even only drinking a half a can I feel weird.... almost a little dizzy... it's a weird feeling. But sometimes I don't have any side effects from it. 
And every time I drink it I alwaysssss have to go to the bathroom like 5 minutes later so I like that it also helps clean you out as well as every other benefit.
Does this happen to anyone else?? 
Is there a similar pre-workout drink out there that doesn't give you weird side effects? Id like to feel like I'm not about to pass out lol

Answer

I like the brand cellucor and their c4 pre workout is awesome, never made me feel weird but it did help me use the bathroom lol
