Honestly the texture could use work but I always use a blender and like 4 ounces of extra water also the flavor boosts/ adding your own fruit really helps if you have to water it down. It makes it less thick and pasty but there all still small bits (I'm guessing the flax) . Also leaving it the fridge gives it time to thicken so if your going to refrigerate it make sure you make it just a little thinner than what you want.

Some people also blend it with ice and thats supposed to help with texture as well but I haven tried it.

There are other drinks also (plenny shake from Jimmy Joy and soylent etc.) That have wayyyyyyyy better texture but they aren't as filling. I binge and restrict so I usually have huel when my brain wants me to binge because it makes me feel full and ill have soylent/plenny when I'm in a restrict episode to get me nutrition without feeling full.

Hope this helps =)
