I have used the 'official' V1.3 and V1.4.
V 1.3 - no sodium, used for 2+ meals a day, by dinner I was craving anything with salt. Adding table salt gave it a funky taste...
V 1.4 - added sodium, but I backed down to 3 lunches a week. Just enough to simplify my diet and routine.
With any major diet change, it takes me about a month for my body to adjust. Taste is generally pretty bland. V1.4 tastes a little weirder than V1.3, and both versions have a slightly grainy texture. I've taken protein supplements regularly before trying this, so I was pretty accustomed anyways. IMO, most protein supplements taste better and fluidize better for texture.
I cancelled my subscription; my supply was growing too quickly now that I only use it for 3 lunches a week. There are cheaper protein supplements out there, and carbs are easy to come by...
