Thanks for the replies everyone. Yea I can keep food down, usually I only vomit around 5-10 times a day in the morning I just had a really bad day that day were I vomitted in the morning then midday then at night. I vomit whether or not I have eaten or not and all at one time...once I start I keep going for about 5mins then it's over for the day except I still feel nauseous all day and I drink heaps so I don't think I am at a risk of dehydration.
