Both tempus and repo gave you sound, valid advice. When I apped for 4 cards last August, my EQ score took a hit similar to yours. I winced, but realized that this is the price that's paid -- score wise -- when adding new accounts. The only real solution is to "garden" -- ie: sit back and allow the accounts to age, don't apply for anything new, and wait for the new credit "ding" to fade. Time and using your new accounts responsibly is your solution.
BTW, my EQ score has bounced back and is now higher than it was at the time of apping. Gardening works. 
Current Scores: EQ 775 (03/04/2014), EX 756 (03/01/2014), TU 760 (03/01/2014)
