Hi Doctor, I started to vape on April this year but not frequently as im not a heavy vaper and i am short term too that i can easily stop vaping. But 4 to 3 days ago, i can t sleep at night, heart palpitations and sweating but the next day, my heart palpitation got better but i was still sweating, shortness of breath, nausea & now i keep on burping to the point it irritates me.. is this a side effect that nicotine slowly healing from my body? And im going to visit the doctor later evening. Thank you
