Doctoring up vanilla shakes

 i typically make mine with ff lactose free milk and ice, makes it more like a milk shake and i nearly always add sf pudding mix...my only delima is the pudding mix makes it start to set up like PUDDING if i dont drink it fast enough...anyone else have that problem?I make mine in the blender with ice...i do the ice and milk 1st, then add my protein powder, then add the pudding mix...

Yes, mine starts to "set" also if I leave it sitting for a little while.  I make mine in the blender, then drink it out of my blender bottle so I can keep shaking it up in between sips.  That seems to keep it in liquid form.

Does the sf pudding mix add calories?
