I am almost to my 5th week post-op. I have officially lost 31lbs per my doctor's visit on 6/15/12 ! I am steadily having problems drinking my protein supplements due to uniformity. My doctor doesn't recommend using a blender to add items to supplements until about the 6th month out due to added air it adds. A relative and another acquaintance say the protein is more important to go ahead and use the blender. What does everyone else think? Thank you in advance for your help!!
