I gained a pound... in one day like that... I think that is water weight gain,
not tissue.

I take my taurine in the morning. My husband takes his inositol in the morning too. Neither of us notice any sedation. I can't tolerate high doses every day
of inositol however. So I don't take it as often. It makes me jittery/over reactive.

Methyl B12 and tryptophan can sedate. Take at night only.
The R-lipoic acid I find, jazzes me up like caffeine, so I can't take that at night. I take my SAMe in the morning. Any B-complex and/or folate take early in the day.

In general when your insulin is working better, you will feel less tired, esp after eating. Anything high carb also creates sedation...because it stimulates serotonin. So save your "treats" for dinner (later in the day).

I find a high protein breakfast is best for me. I then eat a smaller lunch (sometimes much smaller) and a small dinner. I work best on a good solid
meal for breakfast. A high carb breakfast is just a bummer for me..I can go back to bed on one.

As far as cinnamon goes, only the CASSIA form has shown usefulness.
Cinnamon spice may be a mixture of other types.
And you need at least 2 grams a day.
This explains the types:

If purchased in capsule form, you can read the label and see what you are getting. Spice from the grocery store may not be what you think.

Dr. Jensen-Kittley recommends both inositol and taurine in her book and online.
