Morning sickness question

Hey ladies!

I just started experiencing morning sickness yesterday at exactly 6 weeks. I'm wondering how many of you who have been through it can tell me if yours pretty much stays consistent everyday (same feeling, same time) or do you find that it has gotten worse over time? I'm trying to make plans and a few weeks from now and want to be able to follow through. Right now I feel incredibly hungover with a headache, slight nausea and just icky and tired. Thanks!
