Nope,way too much, you'll actually damage your body doing that much HIIT cardio, HIIT was designed to be used only 3-4 times a week so your already pushing it by doing it every day of the week (which is what I do) just follow this - on Mon-Thurs do 15 minutes of HIIT jogging, followed by a 5 -10 minutes slow jog to cool down. Then at night lift your weights. Then on Fri-Sun do you HIIT jogging for the same amount of time and then at night either do 20-30 minutes of swimming or pilates (I'd learn how to do pilates, it increase your flexabilty while toning your body in a lean way). OR on the Fri-Sun you can jog in the morning for 30 minutes and then at night do HIIT swimming for 15 minutes then swim at a normal pace for another 5 minutes
also don't be to discouraged if your losing fat more slowly doing this, it's actually better that way. The slower you lose weight the less of a chance that you'll lose muscle and/or get alot of loose skin around your stomach, and if that happens then you'll never get that 6 pack unless you go into surgery for a tummy tuck.
And I forgot to mention before congrats on losing all that weight!, but now it's time to slow down unless you want all that loose skin on your stomach .
