Hi Jessgentry!
Welcome to our community! I'm so glad you found us.
If you haven't yet, it would be helpful for you to start with reading through the thread at the top of the forum titled,"New to Lyme?...Start here!!", as it is packed full of important information, symptom lists, helpful links and pdf's, how to detox when one has these infections, information on probiotics and much more.
And, here's another good place to find helpful detoxing routines:

I don't use Cowden's so I could give you a wrong answer - and I don't want to do that - so I'll leave that question for others that are more familiar with using Cowden's. Generally speaking a bit more water won't hurt, unless you are using it for an "immediate relief".
But I did want to welcome you to our community!!
