Try not to stress yourself out so much. The NCLEX really is not that bad. I studied 3-4 hrs a day with Kaplan, Saunders and I did practice questions on Facebook from Pedia and ATI. I also found some old Kaplan Qbanks and I had a few apps on my iPhone (all free).
I think Saunders was great for review.
Focus on infection control and labs. There was some meds but not that many on my test. Just try and memorize the basic categories so you can recognize any meds that you don't immediately remember what it is taken for. Also try and memorize the most important ADR to watch out for. For example ototoxicity, hepatotoxity.
