Protein Drinks causing nausea?

The last two days when I have drank a protein drink it has caused nausea.  This is the protein powder I've drank since surgery, without problems.  I haven't vomited, but my stomach is queasy.   Has anyone else had this happen and any suggestions?

 I became lactose intolerant after about six months.  If you are mixing with milk, try switching to Lactaid.

i had the same issue even after switching to lactaid and soy milk... i found that muscle milk lite does not make me feel this way though! Its milk/sugar free and i think gluten free...not sure why but i have no issues with it and it tastes pretty good!

I have been having the same issue. I found that I can handle different flavors of the same brand- just not the chocolate.

I had alot of problems with protein there for a while. I switched from Milk to Almond milk first.

What I think it finally came down to was drinking my shakes too fast. Meaning I was drinking a 8-12 oz shake in about 15 minutes. Blech....

Now, I have to take my time...I usually take at least 30-45 minutes now and I dont have a problem (unless its a flavor I dont particularly care for)

Have you tried blending your shake with ice to make it like a Frosty? I never felt sick when I made them like that.

Hope you are feeling better!

I have had this problem with protien that I loved and agreed with me for the longest time and all of a sudden started feeling nauseas everytime I would drink it. I am not lactose intolorant.
Someone suggested I may need to switch to Isopure protien (Isolate).
I tried Nature's Best at GNC the pre mixed bottles 40 grams of protien. It's not milky it's more like juice.
It's pricy at GNC but found it cheaper by the case at ? Vitamin Shop? Check around for pricing.
I have had no problems since swithching.
Hope it helps you.
