I have been taking 10mg of Citalopram for the last 5 weeks without issue (bar a few initial manageable side effects). The plan was always for me to go up to 20mg which I started last week. I am sooooo tired since I started the 20mg. I’m yawning constantly and feel shattered all the time. The last few evenings I’ve been going to bed at 9pm as I can’t keep my eyes open. I'm normally very active but right now I have no energy. I normally take my tablet in the morning with breakfast. The extreme tiredness usually kicks in shortly after lunchtime/mid afternoon. I wondered if anyone else taking Citalopram had experienced this? I’m hoping it’s a side effect that will pass otherwise I may need to consider going back down to 10mg or coming off them completely as I can’t function feeling so sleepy, especially as I have a young family so need to be on the ball. Thanks.
