+# Start Amphetamine Session With AppleScript
+
+I use the _Amphetamine_ app on Mac to keep my computer from going to sleep
+during the day. It is a menu bar app that can be used to start a _Session_ of
+time where it will keep your computer from going to sleep. At the start of my
+day, I'll typically start an 8 hour _Session_. This is useful if I have to step
+away fo 10 minutes or if I'm doing some writing in my notebook, my computer
+won't go to sleep on me.
+
+Though these sessions can be controlled from the menu bar app, I was excited to
+learn that I can also programatically start a session with AppleScript.
+
+Here is how to start a _Session_ (overriding an existing session) with options
+that specify it is 8 hours long and the display should not be allowed to sleep.
+
+```bash
+$ osascript -e 'tell application "Amphetamine" to start new session with options {duration:8, interval:hours, displaySleepAllowed:false}'
+```
+
+The `interval` could also be `minutes` and then I could change the duration to
+an amount of time that makes sense in minutes, e.g. `90` for 1.5 hours.
+
+Note: the `with options {...}` segement is all or nothing. All three need to be included or don't include the clause at all.
+
+Additionally, a session of indefinite duration can be started by including no options:
+
+```bash
+$ osascript -e 'tell application "Amphetamine" to start new session'
+```
+
+And any existing session can be ended with:
+
+```bash
+$ osascript -e 'tell application "Amphetamine" to end session'
+```
