Morning sickness worse

So I've had morning sickness nonstop since week 6 of my pregnancy I'm now 7 weeks 1 day. The doctor gave me diclegis to try out it seemed to take the vomiting away for about a day but the nauseousness was still there and vomiting returned the next day I haven't even been able to keep water down. It usually subsides about 4 o'clock everyday but it's like I can't even function til then. Is there any other medication that has worked well for you that I should ask my obgyn about?
