Can't keep anything down. Tips?

I'm 6 weeks tomorrow and could hardly keep anything down today, I am so sick. Definitely worried about working these next few weeks like this.

I'm looking for any tips to help with nausea/vomiting, as well as any food/snack ideas that are best for when nothing seems to be sitting well (simple/bland things I can grab easily without much prep to stay fed).

If you don't have any tips, I'd also love to hear your experience if you're feeling the same or have felt the same in previous pregnancies. I am a FTM so I'm feeling very emotional. I am just a blob on the couch since Friday constantly fighting back puking.
