I take medication for anxiety and i usually take Sertraline brand Sandoz, but last week at the pharmacy they gave me a different brand called Sertraline SUN.
It seems since i've been taking it i've been feeling a lot more sleepy.
Like my eyes feel heavy and i feel so tired. Also i feel a little off...

Could this be due to switching brand?? or is this a placebo effect and i'm overthinking it?
