Diagnosed with SAD ( Seasonal Affective Disorder )
My psychiatrist prescribed me Clonazepam (0.5mg) + Escitalopram Oxalate (5mg) at night  &amp; modafinil 50mg in the morning

I've been taking it for 3 days Clonazepam and Escoralopram makes me sooo sleepy and I end up sleeping for 12 hours+ on the first day 

Talking about modafinil 50mg I don't think it works for me 

Last night I took Clonazepam + Escitalopram at around 11PM and I woke up around 9 AM ( feeling sleepy) after my breakfast I took Modafinil 50mg and I Again slept for 4hrs 

I woke up around 2PM I don't know if moda 50mg is working for me or should I up the dose

I took a vitamin D test and it was 14.0 ng/ml 

I don't know if i should continue taking antidepressants and moda or should I treat my vitamin deficiency.

I don't know if it's SAD or it's just vitamin deficiency
