Eczema Treatment Care

when i was pregnant with my first child 18 months ago i developed atopic eczema all over my body, i tried every cream on the shelves and antihistamines along with steriod cream
it looked like i had been burned by a chip pan and felt like hell i couldnt bare clothes on my skin and soon i couldnt sleep or go out much and developed depression.
now i still suffer with eczema but nothing like i did and its very controllable!
what i wanted to now is if any one has had anything like this and if its likely to happen again if i become pregnant again??
any prevention ideas would be appreciated to ( besides the idea of not getting pregnant again)
