No shortage here, but you could be experiencing the supply chain boondoggle.
If you'll allow me a suggestion, get Trader Joe's whey powder, make a batch of Magic Milk, bite the bullet of self discipline, and make sweet or savory smoothies.
I think Premier Protein is a scam. IMO. But I don't like anything going into my body unless I know its ingredients intimately. You can easily make batches of your own and refrigerate it in airtight containers in the fridge.
I don't like to sound harsh, but woman up, girlfriend! YOU have the power, A to Z. Do you want this, or did you have surgery expecting magic? This is DEFINITELY not the easy way out. But you did the "drastic" thing already. Protein intake is nothing compared to everything you've already done.
Sorry about the tangent. I'm just stunned by people in general, complaining or failing in the face of geophysical danger. Breathing and eating are simple and involuntary compared to what so much of the world is suffering. I spent an hour on the phone with my shrink yesterday talking about it.
I definitely need a spa day at the YMCA, but... fucken COVID... I'm crabby.
Oh, one more thing. Freeze your PP shake in the ice box and eat it like a fudgesicle.
