Yes, that’s right — a “meth comedown” (or “crash”) is when, after a high, your energy instantly disappears and you fall into a deep state of fatigue. Symptoms often include depression, panic, anxiety, and, to top it all off, a desperate desire to get back to “free time.” For some, this may only last a day or two, but in the case of long-term use, it can last for days or even weeks.
