im 18 weeks and I thought I was over it but i `m still puking !!
I personally havn't experienced this but I worked with a girl who had a wonderful first trimester and then got really sick for the whole second trimester but then felt great for the last one. It seems that it has no rhyme or reason sometimes. I am sorry that you are so sick especially when everyone tells you the second trimester is the best, I hope that it goes away quickly for you.
