My cat has tapeworms and hasn't eaten in two days?

My cat has had tapeworms for a will say maybe 5 days since I noticed the first worm! That day I checked her stool and didn't find any but maybe they were covered well in between the litter, checked again the morning after and again nothing to the eye so I thought it was a false alarm! Well she had gradually decreased eating until yesterday her first full day without food, she's been puking since the day before yesterday also and again didn't think much of it because she gets hair balls every now and then but it escalated! I bought her her fave pâtés yesterday to see if she'd eat but nothing, tried again today in the AM and still nothing! I checked her barely stool today and it was covered with tapeworms, also a barf in the AM had tapeworms and a little blood!

Tomorrow I will be taking her to the vet! Any advice until then? I have 50 and fear the ER will be more than that, any advice up until then?!?! We have also gotten rid of the fleas!
