My toothpaste makes me vomit

Yes it really does. For the last month or so, I have felt sick each time I brushed my teeth -- morning and evening. At first, I figured it was due to the *gasp* glass of wine or two I had consumed earlier in the evening, but when it happened after not drinking and in the morning, I must blame it on the toothpaste. And finally, last night, it happened.

Not sure what to do about this....
