Am I a Dunce- Please Help Me Cross Post VSG/Nutrition

I just tried making my first protein drinking using Unjury and Crustal Lite and I am confused. I used half liter bottles of water and I had a terrible time getting in Unjury in to the bottle. Finally I found a funnel but even that was hard cuz it kept getting clogged. Is there something obvious that I am missing.  I want to keep using the half liter bottles cause they are so much more convenient than quart or gallon containers and I do recycle the bottles in our local recycling bin.

You'll have better luck if you mix the shake in a shaker bottle or a blender.  A shaker bottle will have some type of "device" inside to help break up lumps.  A salad dressing shaker will work too.  The one I have has a metal whisk like ball inside.  A salad shaker has a little wagon wheel plastic thing inside (a friend found hers at the dollar store).  If you put the ingredients in a blender, just whiz is on low until it's just mixed.  If it's too foamy afterward, just let it sit for 15 minutes or so until the foam goes down.  Or add ice cubes and make a shake that's like a frosty or ice cream. Once you have it mixed, you can put it back into the bottle if you'd like.  But mixing it in a bottle will most likely result in lumps. Pam
