4 weeks taste stays in mouth?

Every time I eat something the taste stays so strongly in my mouth! It’s annoying. I’ve tried brushing, flossing, using mouth wash, adding gum. Maybe its just more noticeable but it’s so annoying. Same thing when I burp. A little of the smell of what I ate comes up. Maybe I’m just finding everything irritating bc I have a terrible two at home w me all day, a crazy MIL who we’re staying w & then this crazy hour job plus military my husband works, no appetite, all day nausea... so annoyed these days.
