Effexor and lunch

i was prescribed this drug to help depression/gad/ocd. i chose the drug myself after much research. while i feel much better since taking it, it seems that since my dose was increased to 150 mg that i toss and turn for about 2 hours a night - while i'm asleep. this is what my husband tells me. last night he timed my tossings and it occurred about once every 5 minutes for about 2 hours. i also get somewhat violent and have punched him, but that is rare. i'm going to start experimenting with the time i take my dose, which is at night. rather than take it a couple of hours before bed i'm going to take it right before bedtime and see if it stops.

i also notice that around 2:00 pm i get very drowsy and feel like i could fall asleep at my desk at work. this mostly happens when i eat a heavier than normal lunch.
