I take Walgreens brand multi vitamin everyday for years now. They aren't huge horsepills and are really easy to swallow. They make them w/ or w/o iron (I take w/ but like sage said if you wanna stay away fromt hat its fine ... truly tho the vitamin is OK).
As far as it making you sick, the vitamins are what we are supposed to take in thru food so unless you take more than the recommended dosage or have an allergy to a particular vitamin(which if you did you'd know by now) there isn't a reason to be sick from it.
I know its hard but try to remember it was the taste that made you sick ... when you were a little kid no less. You could probably take the exact same one now and not get sick off of it as you are older (tho I wouldn't try it again, cherry tin can doesn't sound tasty lol).
Oh, another thing, take the vitamin after a meal (even a small one like a cereal bar which is what I personally have) and the pkg says w/ a full glass of water which I never do but you might want to just to keep your mind at ease. Good luck, you will do fine!
