have heard that peppermint tea can help. I think i read that a current pregnacy/birth magazine, check it out before hand thou.. But, i think its just one of those things unfortunatly. As dh says to me, 'its all for a good cause'

I am lucky, mostly in the office on my own, so tend to be able to toot away as i please
You might also find that some foods that you normally wouldnt have a reaction to (eg onions) you will now as you change. I know my sister couldnt eat chilli anymore. So, maybe keeping an eye on what you eat, and the level of 'gas' might help figure a few bits out.
