Yea you're right, i found my problem is about adaptation, before I start, I don't really into breakfast but now breakfast seems to be a must, body has already get use to it. I guess it takes time for my body to adapt more food intake. And also discipline.
I roughly got the my lunch by 1.30pm include travel to the restaurant,takes me 20min to finish, Im slow eater. Tried take only dishes and I was WTF the price,even for chicken rice stall. And yeah seriously not enough power and I do need to slot in 100plus during training to slightly give some extra energy to continue, as the weight I can lift is getting heavier, also has been reducing the calories burn of by the warm up cardio from 5min to 3min on treadmill. Maybe I should adjust the pre workout meal to 1 1/2 hour before workout, let more gap between lunch and pre workout meal.

Thanks for all the replies   

cut down ur time (10 mins rest/carry ya bottle around u) or some of ur routine/reps...the key is keep it simple go home and rest..ya muscle will be grown when u get good rest.. 

Edit: personally i dont drink 100 plus  during workout or any other days...up to u.. i actually have almost same routine like ur (except i combine back with triceps cuz back already eat my biceps...and chest with bicep..and lastly legs)..i try to keep it short dont talk to ppl around 2 much..and i still can maintain around 50mins-1hrs..

if bench not available go for machine instead dont wait..next workout u can do free weight..
