For experienced pregabalin users: How can you keep the magic, euphoria, and anxiety-relieving effects of pregabalin?

This is the first time I’ve tried pregabalin. The first time, I took 300 mg in the morning and felt euphoric for about an hour, dizzy, and, to be honest, completely free of social anxiety—I was talking to anyone who crossed my path. However, the next day, 450 mg barely worked, and the following two days I doubled the dose again, to 600 mg and then 1200 mg, with no effect. I didn’t feel any of what I felt that first day anymore. I rested for four days, from Sunday through Thursday, and on Thursday I took another 300 mg, which brought back some of the anti-anxiety effect, but I’m no longer euphoric—none of that. And it didn’t do what I expected in terms of anxiety either. My question is, how can I make sure I don’t lose that magic of Pregabalin? So that every dose works really well, or so I can get that effect like the first time?

In my country, pregabalin isn't a controlled substance, so I don't worry about getting it—and I'm not sure if that's a good thing or a bad thing—but yes, I'm building up a tolerance to it really fast, and I don't want to lose that magic
