To Port or not to Port

Hey guys, I've been over this subject matter before, but I'm still not sure what to do. My veins were accessed for chemo treatment and everything went smoothly until the Taxol caused a complication and I needed an epipen. Three days later, when I went for the treatment again my veins hid and it took 3 nurses to find a vein in the back of my hand. Now I have to go back at the end of the month and I was leaning toward the idea of a port, but I was told the port would stay one year after the chemo was finished. Not sure if I want that, but what if my veins go in incognito again? Other than drinking tons of water are there other things I could do to coax my veins out of hiding? What say you honorable cancer patiens?
