Really Need A Break

Do I sound unreasonable by probably hitting a bar or club and have some drinks while partying for a night? I really really really need a break! But I feel guilty if I were to let my hubby take care of our baby in the night while he needs to work the next morning. But I really need a drink and a fun atmosphere! (not breastfeeding anymore) Should I go? My baby is 2 months old now. Or should I wait till when my baby can sleep through the night? But I feel that anytime I may go berserk
