@cloud60 from the insert:

Dizziness or fast heartbeat may occur within 4 hours after using this medication. If these effects occur, sit or lie down right away. These symptoms usually go away within a few hours. These effects should go away after several doses as your body adjusts to the medication. Redness/pain/swelling at the injection site may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.

ps I did 8 clicks yesterday with few side effects, and today I did 7 and am in bed. It varies from day to day! If you have something important to do, once you get up to a higher dose, you can back off a click or two to function!
