How to get anything done with sickness!

I'm 8w4d with my first and the morning (all day) sickness has been going strong for almost 3 weeks now. I'm super thankful I haven't actually vomited yet, but I feel like I could almost constantly. I can barely eat or drink because my stomach is so upset. I work at a desk so I can rest periodically but when I'm home, I'm bound to the couch. I've tried Sea-Bands, snacking, Unisom and every ginger thing available.
