Garlic intolerance = digestive nightmare!

I have found that if I accidentally consume garlic (usually because a restaurant served it or I was not diligent in avoiding it) I can counteract some of the reactions by immediately taking Gaia's Gas and Bloating pills and one or two peppermint pills. Depending on how fresh the garlic was, and how much I consumed, it can lesson my reactions by up to 75%. I will even take it prior to going out to social events as a precaution.

One more comment, garlic has sulfur in it, and someone I knew some years ago was sensitive to sulfur. (She learned this when the town's water supply got a high sulfur content).

So you may find that different things in the same food might be the allergenic agents.

After many years of feeling this way, I decided to look online to see if this is a problem with anyone else.
I have a self diagnosed allergy to garlic. I find that when I am cooking at home I can use a small amount of crushed garlic gloves for flavour. My problem seems to be with garlic butter and oil used when eating in restaurants. I was at an Asian restaurant last night for a friends birthday at approximately 8:30pm. I ordered ribs for a starter and duck with mango slices for my main course, with noodles - thinking this would be okay. I also did not have any alcohol.
At 3am this morning I awoke with severe abdominal pain; followed by a very violent strain of vomiting and diarrhoea lasting at least an hour. When I finally went to bed again I nursed a very sore head and tummy upset. This morning, I am extremely weak and desperate to ask if there is anything that would help me now or in the future?
I have found restaurants to be generally very unhelpful when ordering food and explaining about my allergy, usually telling me there is no way the cat majority of the menu could be cooked without garlic!
Maybe some is aware of foods that would make smart choices when out to avoid this problem.
It's sad to see so many other people with the same issue and it's even more sad that garlic is my favourite taste!! Ahhhhhhh x

I have developed with age garlic and onion intolerance as well. One meal of Italian restaurant cooking sends me straight to the bathroom. If I cook at home, I have found I can use a small amount of garlic powder and/or onion powder and be fine. But the problem comes the next day when I reheat leftovers and eat them. Then the same food I ate last night suddenly gives me boating, gas, and cramps. Any idea why?
