There's not much a hospital can do beyond treat your symptoms. Your major concern is loss of taste and smell. This is not a life threatening situation. Add in a few more symptoms if you want to be admitted...mental confusion, neck pain, nausea. Hard to fake a fever, dry cough and vomiting, diarehha, but combined with shortness of breath, rapid heart rate, turning blue and maybe you'll get in.

Sounds like there's a bit more behind your motive to be hospitalized. I hope you find an alternative, hospitals are not a great place to be now.

Drinking tonic water is another suggestion I read about on glp. Tonic water with quinine. Quinine is used against maleria, maybe it will help you feel more proactive.

Are you taking steps towards not being transient or is it a choice you want to continue?
