"i take welbutrin xr, so it takes a couple to a few weeks to kick in and wear off. i didn&#039;t like it very much when i first started because it really didn&#039;t feel like anything changed for me. i never felt like i was on medication at all, i just felt normal. but i talked to my doctor about it, and he pretty much explained how that was exactly how it&#039;s supposed to be. so ever since then, i&#039;ve been hopelessly devoted to my welbutrin xr."
