My advice would be run on an empty stomach in the m,orning. Stock up on canned food, such as tuna and chicken. Go to an online supplement store such as DPS and buy some protein bars (for those times when you need a snack, so you don't eat crap) and if you want a shake mix that is hella not clumpy, go with isopure. Also you said you mix your shake with milk; if you are trying to cut out I would use water instead, no need for the extra cals. Also water will make it less clumpy. Make sure to continue to hit the weights hard to preserve your strength and muscle.
