I used to take it 3x per day at 800mg each time. For anxiety. But I find it tends to fizzle out if you keep using it.

I now take it as-needed, 800mg. It helps with anxiety that way. But it only has a subtle affect. It's not as good as a benzo. But it does help.

I have not had any problem with weight gain, whether taking it daily or as-needed. But I have heard that people can have weight issues on it.

It is also known to make people sleepy, but that isn't the case with me. In fact, it tends to make me more awake.

Hope that helps.
