She has to be seen tonight. Not wanting to eat much for two days is bad enough. Vomiting 6+ times and lethargy too - this should not wait. No drugs until after the vet sees her. Withhold food for now (because her stomach needs a rest and because on the off chance it's a blockage, that isn't going to help the surgeon any).
There is almost always an ER vet withing a couple hours. Hopefully you have found one and are on your way.
