Morning sickness....still

So I had all day nausea since 5 weeks. No throwing up, just intense nausea all day. I was on medicine for it. I started feeling better at 12 weeks and boyyyyy was I wrong. Now I no longer feel nauseous all day, instead I have these sneak attack run to the bathroom immediately episodes out of nowhere. I go from feeling completely fine to dry heaving without warning. I was hoping this would be ending...,not transforming to something worse. This sucks!
