I just started on my first Huel shake/drink I'm not entirely sure what to call it when you just mix it with water. And though I would start a thread for reporting experiences.
I mixed the Vanilla and eyeballed the odd 70 ml. Between the powder and water it was pretty much at the 600 ml line on the shaker bottle. I have been drinking it slowly as I reply to things online after going for a run.
My first reaction was that it tastes "raw but not unpleasant." The flakes are enough that I find myself wanting to chew, especially after I swallow, but that does not bother me. I am not around a mirror, but I imagine the ones that are left behind are visible, so having some water handy to be able to rinse them off when done might be good. I also noticed a lingering sweetness that at first was distracting but as I keep starting and stopping my drinking I guess I have grown accustomed to, but another reason I might want plain water as a chaser (NB. I am pretty sensitive to sweet).
I think it settles. I feel like these last ~200 ml are thicker but I may be imagining it. It has been 50 minutes since I mixed it. Something I may need to watch, and if it is the case just sake every so often if I am drinking it slow.
Stomach feel was good throughout, except for the relatively quickly pounding back the last 100 to 200 ml, that caused some discomfort in a feeling of heaviness. There are lots of possible reasons: because at the end it was so thick, because I was getting full, because I did it so fast, or because I am not accustomed to eating so much. Chasing it with some additional water (400 to 500ml) seems to have helped.
I ordered one bag Vanilla and one of the Unflavored so now I am very curious what the unflavored will be like. I am only traveling with the Vanilla at the moment though, figuring I would finish that before starting on the Unflavored.
