Working out and I can't move!

So I started a "fittest loser" competition at my work gym, and yesterday I worked with my trainers really hard for the first time. I usually work out 3 times a week, 30 min on the treadmill or elliptical and I feel like I get a great work out but tonight I can't move. Yesterday I did 20 min spinning and 10 min intense ab work and today more ab work and leg work. I have never worked out so hard in my life to the point that I wanted to throw up and my face was red a good hour after my workouts. Tonight I am so sore I am drinking a glass of wine trying to get relaxed but it hurts to breathe my stomach muscles hurt so bad.. Anyway my eating is better, but I know I need to get more serious and probably drop the wine at night but it's my pleasure of the day. I weighed in Monday and I am back to the weight I was a few months ago, so I want to loose 20 lbs by April 24th, when I leave for my trip... Can I do it? Stay tuned! :)
