I don‘t feel pregabalin/lyrica. Why could this be?

So I got myself 10 capsules of 300mg Pregabalin. I decided to start slow since it‘s supposed to last the whole day.
I heard it‘s best to take on an empty stomach, but I already ate and still wanted to try it, so I did it on a full stomach.

I took one capsule and divided the powder in three parts. So approximately 100mg each. And I only do it orally.

0:00h I took the first 100mg.

2:00h I felt slight foggy in my head but nothing else. I took another 100mg.

4:00h Nothing changed from the effect. I took the rest.

6:00h (now) I think I feel slightly relaxed and my head is still a bit foggy.

What could be the problem? Full stomach? Natural tolerance?

I was pretty excited to try this substance since I‘ve heard people claiming it‘s awesome and unlike nothing else.

Any suggestions?
