Is anyone else absolutely miserable?

I'm 10 weeks and I'm just so sick and tired. My head hurts I'm nauseous and throwing up almost every single day. I have no energy from a combination of all of those things. This is absolutely miserable. Once in a while I'll have a good day where I can eat and only feel slightly nauseous but overall I've been losing weight. I wake up feeling like I'm hungover or something. My doctor gave me Reglan which was helpful but I ran out of it just before thanksgiving and haven't been able to get my prescription renewed. 
Is this going to get better? I can't do this for 9 months
