Awesome, I hope it's helpful for you!

My experience is that it has a noticable effect about 30 minutes after ingesting. I'm currently taking 100 mg tablets. I had done a liquid suspension, but tablets are easier and more consistent.

If you don't notice a difference in the first few nights, it probably doesn't work for you, but b1 seems pretty inexpensive to try.

It doesn't seem to be like some things where you have to use it for two weeks before you notice a difference; but also there's not much (if any?) residual effect. Maybe I can forget to take it one night, but on the second morning, my spouse will ask me if I've been taking my B1. But, sometimes I do have episodes when I have been consistent, so not a silver bullet.
