zero carb isopure making me sick

[warzchit]

i bought natures best perfect zero carb isopure so i can take as a snack and up my protein intake. the first time i took it i felt weak and had an upset stomach. the second time i took it was post workout and it made me vomit about an hour after i drank it. the third time i cut the serving by half (1 scoop) and it still made me feel weak and have an upset stomach. i just want to know if anyone else has had this happened to them or know why its happening to me.
thanks in advance for your response...

Some people have problems with large amounts (10g+) of glutamine at once, but I'm not sure how much that has. I'm guessing it can't be any lactose intolerance if it's isolate. Do you have any adverse reactions to artificial sweeteners?

this one has 4.6g of glutamin and no i dont have adverse reactions to artificial sweeteners use splenda and truvia sometimes

Have other proteins in the past caused similar problems?
