Nausea is Here To Stay

Spent the morning at the Emergency room.
Continuing to vomit, lose weight, become weaker, and this nausea is out of control! 

After four attempts at an IV, I received some Gravol, then some Ondansetron shortly after, then Diazepam, then more Gravol, and somehow, walking from the chair in the ER to the washroom brought the nausea flooding back. I have never had absolutely nothing help it. 
Looks like the nausea is going to be my friend for a while.... 

When they discharged me because they thought I was feeling better, should I have hobbled right back in when I was hunched over a puke bag right away? Is there really anything else they could have done for it short of knocking me out completely? 

All I can do right now is take my Transformer Anti-Nausea med and sleep. All. Day. 

Gonna be a long haul. 

P.s. - no I am not preggers.
