Can red bull cause throat problems?

I'm not a doctor but I've narrowed down my weird skin flaking and flaky scalp to the frequent usage of Redbull. Seems that when I drink Redbull too frequently my Rosacea/Dermatitis like symptoms flare up from some sort of detoxification from the over abundance of Redbull.

Could be some sort of allergy symptom as well. However I'm guessing that the allergic/detox reaction is due to my body trying to rid itself/overeact to whatever is in the drink. As soon as I'm off it for 3-4 days the symptoms start to clear up. Odd thing is there are some good vitamins in the drink so maybe next step is to narrow down what isn't good in it that is causing this reaction.

Wonder if people experience the same?
