Medication, stutter and functioning.

Medication, stutter and functioning. I have seen numerous post regarding people taking anti-anxiety medication and/or anti-depressants etc. Just out of curiosity, does this have an effect on your speech? And are you able to function normally? For example, I am a student and need to study a lot. Whilst on anti-anxiety meds would you be able to study and perform detailed, complex tasks etc? The idea many people have of these sorts of meds is that they make you slightly foggy and so on. I'd like to hear peoples experiences of this/ Thanks!
