Prego + hot weather = no Bueno

So I've never really had much for morning sickness. Just a little nausea and dislike for food. But, living in Cali, it's gotten really hot and tho I'm in my second trimester I feel like now I have morning sickness. The vomiting, diharea, dizziness and headaches and it's awful. I'm pretty sure it's the heat. Anyone else experiencing this? And how do u beat the heat? TIA ❤️
