> So, you have been cutting back carbohydrate?

No, haven't started yet... but I did it a couple of times in the past. Lost
8 kg in 30 days and never extended this time. The problem is that I had a
hard time in keeping this weight due to own human weekness (craving for
other food, sweets, etc.).

Yes, if you are forced to purchase them in pharmacy stores. However,
yesterday I found a variety of vitamins (including "multivitamins") in my
local 100 Yen store. This problem should be solved by now. Need to get the
test paper stripes for ketone testing since tasting the stuff isn't what I
have in mind. On the other hand there are millions who drink their own urine
for medical reasons... (google a bit and you'll find tons of information on
it)!
