Dehydration while breast feeding

For 2 days now I've been running a temp of 100-100.2 and I have body aches, headache, chills, and I feel terrible. I know I am dehydrated because I pump so much and I have barely been drinking water. I've also been dehydrated like this before. I am trying to avoid the ER since I have a 2 week old.

So I've been drinking water, Gatorade, and taking acetaminophen. Is there anything else I can do?
