It was during the Soul shock moments that I experienced constant nausea and I always had to puke to feel better. I realized this later on that it was my Twin’s Flame’s energy that made me feel that.
I started to learn the difference between his energy and mine and every time I feel that intense energy from him, I remind myself that I can not control it but let it be. Once I do this, it automatically passes but you must learn how both your energies work.
This reminds me though, the first day I met my Twin and we locked eyes; that was the beginning of nausea. The next day I was feeling terrible when I woke up!
Yes, it is normal and it must be an energy merge taking place. This twin flame experience touches every part of your body, mind, and soul.
