Visiting Philippines need some guidance

Good evening everyone, I’ll be visiting Philippines especially in this region for around 2 months for some training. I’m vegetarian and have heard it’s not easy being one there. Just want to know some recommendations on what I can eat or manage to eat there. Also the general things like people, weather, language barriers etc.. One should know. Also i drink and smoke would love to know the famous brands there (affordable and crowd favourite types)
