What is referred to as discontinuation syndrome can occur when one or more doses is missed. Discontinuation symptoms can include: difficulty concentrating
, shaking, sweating, headaches, nausea
, "brain zaps", irritability, anxiety
, depressed moods, hearing things and increased blood pressure
. If you miss a dose, take the next one at your next regularly scheduled time. Don't double up on doses to try to catch up. Since I am answerig this 3 days after you asked, you should definately be feeling better by now.
