--in one dose of 100mg in the morning.

I haven't noticed any "charged up" feeling or effect, but I'm pretty charged up in the morning anyway; I've always been a morning person (notice when most of these posts get made).

I'm thinking of getting some 50mg bottles next time, though, and taking one in the morning and one in the evening. I do have some problems at times with feeling sleepy early in the evening, especially during the short days of winter, and especially if a large evening meal is consumed--I've assumed this is part of my insulin resistance/reactive hypoglycemia, as well as having a seasonal component. I can easily overcome the feeling if I have an evening tutoring appointment or something, but it may be worth the experiment with the R-lipoic.
