What antibiotic are you taking for this? They are all different and some will make you feel nauseous, others not. For instance if you are taking doxycycline nausea is common unless you line your stomach first with something. Milk is good for this but I see that you are on a dairy free diet. Try soy milk or soy yoghurt instead. Or just eat a couple of crackers and drink plenty of water.
Also you will need to take a probiotic after the course, if it is only for a week or for longer term use, take the probiotic at the same time but at least two hours apart from the antibiotic.
