There is an extended release version if it, but if you're taking it to try to get high, I wouldn't bother with it. The dose is like, 12.5 mg or something, if I remember? And the larger portion of the dose is of course not frontloaded. The initial comeup is a lot less strong from them, so it's comparatively lame tbh, and in my experience that's the most important time with this med. In fact, I wouldn't bother with it if you're asking for sleep either, unless you're someone who can get to sleep pretty well and just struggle to STAY asleep.
