My cat ate lucky bamboo and is not feeling well... pls help?

my cat ate lucky bamboo and was throwing up this morning... we took her to the vet and they gave her some stuff to stop the vomiting... she threw up again after that... only twice though and seems to be getting a little better.... i was wondering if there were any suggestions on helping her get better still... i was wondering if electrolytes would help... they help hydrate and also clean the system out... but not sure... any suggestions would be greatly appreciated... and thank you
