Y'see the thing with the oil... I used to take a supplement too, but for different reasons.
Now while they say 'nutritionally complete', given that we have complex and unique physiologies I refuse to believe that we would all have
exactly the same nutritional requirements. Now when it comes to average nutritional requirements, I'm sure all the varieties of spacefood have all the approved amounts of nutrients for the average person, but point me to an average person? (especially as nutritional requirements varey with age, level of exercise, etc, before you even get to physiology).
So, if you feel you're missing out, it's for you to judge, but given these are probably nearly fat free, I wouldn't be surprised if you're lacking lubrication. the only thing i was once warned about with multivits, they sometimes have a sugar coating.
Now, my interest is that given that certain EFAs are essential for brain construction and function, and there is considerable research as to whether a lack of certain EFAs can contribute to depression. Makes sense to me, as every time I diet I get as far as losing a stone or two, but by which point I'm chronically low. Which is what I'm keeping a careful eye on things this time...
Anway, moving on.
Day 4, less spaced out, still hungry, not a ketone hinted at, I don't know what you all mean about
constipation, I've had quite the opposite...

Gut (as well as stomach) has been burbling all day.
No aches or owt, but have been noticably more tired this past couple of days.
Went to Tesco for coke zero, just to console myself with a bit of normality. That was an almost
painful experience. Have been a veggie for over a decade, but nearly mugged the bloke in front of me at the till for his shopping.
I await the point this becomes 'brilliant' and 'easy'. Not cracking yet, but ain't exactly leaping with joy right now.
