Morning sickness? All day sickness!

I am 8 weeks/ 1st pregnancy/26 years old/ U/S 168bpm  and at the start of my 7th week I started getting the "morning sickness" expect it lasted all day! 
​This past week I have been in hospital with IV fluids and something to control my nausea. I wasn't able to eat or drink for more than 30 hrs. I was so dehydrated. I tried everything my mom and I could think of. It was awful!! The emerg doctor gave me diclactin and I gotta say I have been able to keep food and fluids down. I am so thankful. 
Any thoughts on diclactin?
