Does anyone have any experience with Sea Bands travel bands for morning sickness? They work on acupressure. My set just turned up and I tore the packet open and put them on straight away. I am hoping they are going to help but wondering if it is just a mental thing - as in I have them on so therefore I will suddenly think I feel less sick. Thoughts and experiences? Oh and my tub of Preggie Pops turned up too - phew!
