...just wanted to know if it is normal to feel incredibly thirsty after the salt water flush
No doubt, Pippa, I'm on day 2, just got up this morning and slammed down the salt water. By the time I reached work (45 minutes) I was was pasty and parched.
The flush is already working very well and I'm very, very glad I'm not going to be lifting anything heavy today! (I'm still accustomed building houses for a living)
One question, just to double-check, using soy sauce with the flush is cool?
