How often a week do you hit them gym? You maybe are over training mixing Squats with the Bench. Both are demanding (especially) Squats. You would be wise to split those onto their own days to focus on them more and get more sets in. As far as pre-lift boost slam back a black coffee, or preferably take a Caffeine pill. Most stores sell there Caffeine pills in 250-500mg doses which works out to 2-4 cups of coffee. This will give you that rush for the gym. But tweak your routines and times, split up the two workouts and dedicated only a hour, as I suspect you might be in their way longer, what you describe is how I felt when I used to over train. Now I split up my dedicated areas and spend 45min-1hr in the gym and I'm done. Try the tweak if that doesn't work then a coffee or Caffeine is all you will need.
