Can I take Seroquel 50 MG and Ativan 2 MG together at bedtime?

I'm presently taking Seroquel 50 Mg at 7:00 PM and then @ 10:30 PM I take Ativan 2MG, but I've gained a lot of weight because Seroquel makes me hungry and I start munching around 8:00 pm and I can't stop. Therefore, i would like to know if I can take Seroquel and Ativan together before going to sleep. Thanks in advance for your prompt answer.
