How long for side effects of Celexa (generic citalapram) 10 mg to wear off?

I am ending my second week on 10 mg and finding that the side effects in experiencing won’t subside. The drug is making me extremely drowsy/ uncontrollable yawning and feeling out of it and “spacey”  just feel zoned out and mentally slow. Will this subside or is this a sign that my body can’t handle this drug? I can’t take the side effects. I feel like they are affecting my quality of life and work and it’s just frustrating. Should I go off and how do I know when I need to go off if it’s not helping? 

Thank you. Looking forward to your responses! 

Hello

I would give it awhile.  I recently changed from Fluoxetine to generic Lexapro (like a sister drug to what you are taking) and it has been just over a month and I experienced a lot of side effects (still an but has gotten better).  Two weeks is normal to still be feeling this way especially if you started at this dose right away.  I started low at 2.5 then went to 5 and now at 7.5 .  

I understand how frustrating it is to function at life and work been and still there!
