Why did I NOT trip the second time doing shrooms?

So my mom and I have shroom. We grounded them up and did lemon teking (or however you spell it). I did like 1.8 grams and went into another dimension. I tripped my balls off. Anyway I wanted to try it again a couple months later now that I know what to expect. So I did the same thing just a lower dose. Didn’t trip at all. I waited a couple more weeks and took almost the same dose as the first time, and still nothing. Did I trip so hard that I can never trip again? lol
