Yes you can take Effexor at night, I have always taken mine at night, i stated on 75mg and was increased to 150mg, When i first started takeing them as you i felt very tired, but at the same time felt as though i was in my comfort zone, but after about 3 months the tiredness wore off, and now i dont feel tired when i take them, at first i had to take them with or just before food or i would feel sick, but now i can take them any time at night, (sometimes i forget to take it untill midnight) without feeling ill.
I would definately ask your P.D. to change to nght time, but you may feel strange the first time you miss your morning dose, i know if i miss a dose, i get little chrges going through parts of my body, but it subsides quite quickly after i've taken my dose....
