Week 3...cruising to Friday

Are my workouts working? Am I self-sabotaging by eating too much at work because I'm stressed?! It's hard to know. Also--I have been feeling like I'm sleep walking on my way to the gym each day. This can not be translating in to super intense workouts. I'm not slacking--that's for sure. I have been progressively adding more weight. Today for example:
I did 70 lbs on the leg press--I think the machine is at least 45. I was pressing lower and slower in to my body, so I definitely felt more worked this week.
I did 60 lbs on the hamstring and added 5 more for my last 2 sets. I think that's more....
On the wide grip pull down, I did 2 sets with 55 and 2 with 70--those 2 with 70 were pretty hard. I realize it looks like a big jump between those--but you have to adjust with each arm so it's 27.5 on each arm and then to 35. Whatev.
After these, I did the hyper-extensions and ab pull downs and added in 4 sets of reverse lunge kicks. I really like the lunge work. I feel like it gets the last juice out of my legs before I leave.

After my workout, I felt like I should do push-ups and pull-ups....I could stay there forever is the problem.

So, what is my problem? Why do I feel like I'm hitting a slump? I suppose it's a good thing that next week, my workout is all changed up. On the other hand, I think I miss more of the bodyweight exercises. I think until I really get my strength up, the bicep curls aren't going to help me too much. I need to crank out some push-ups, pull-ups and crazy step up lunges.

On the other hand, before I started at this gym, I was struggling to add more pushups. I felt like I had hit a slump and needed to vary my movements with bench press (all angles) and the assisted pull-up/dip machine. I'll figure it out eventually.
