RTD + Powder

I am one week out and struggling to get in my 70-80 g Protein (req. by my nut). I have been using EAS Myoplex Original, but it takes me all day to even get 3/4 of the container in. Yesterday and today, I added a packet of powders?utm_source=BariatricPal&utm_medium=Affiliate&utm_campaign=CommentLink" target="_ad" data-id="1" >unjury. I also mix my Water 1/2 with Isopure and Mio or CL.

Since I can only get in about 2 ounces every 2 hours at this point, I don't feel like I'm overloading with protein at one time. Is this okay? Am I harming my recovery or overdoing it? This is just while on full liquids, unless I can't get enough protein from food in the first part of the next stages.

The nutritional breakdown of my day is as follows (yes, I am a nerd and plan out and log everything before the day begins):

Cal: 395 (I add in some Soup, about 6 oz daily, but it only adds 110 calories, and I don't plan which soup)

Fat: 4g

Carbs: 16 (3 from Fiber, 4 from sugar)

Protein: 75g

So main actual question: is it okay to mix Protein powder with a RTD if consumed over the course of the day?
