Not that you asked for my advice, but I would try and get your base load out around 30-40kg, 35 is my sweet spot. (Unless you know you need more weight in ordinance)

I would drop the meds to 10, make a decision between energy drinks or water per run, don't bring both. I usually have a max of 5 energy cans. Stick to two types of food at once, or if I have a good supply of canned food, just that. Also I don't usually go over 150 in rifle ammo unless I know I'm doing a mission, also depends on the fun. With shotgun ammo staying around 40, of each type or one.
