Morning sickness early

I am only 4 weeks pregnant and have been having morning sickness for over a week already. I have read that it usually really starts around week 6 and was wondering if anyone else got it starting really early and if that correlates to having it much worse then woman who's sickness dose not kick in till later. I'd really like it not to get worse, I can cope with this almost constant queazy feeling but I really don't want to spend the whole 1 trimester or longer over the toilet bowl.
