I wake up every morning with a feeling to throw up, I sit in front of the toilet for 5 min in excrutiating pain because i never actually throw up anything. This only happens when I wake up from sleep. I also get randomly dizzy during the day, very dizzy it stays for 3 seconds and goes away, but it happens often. I also dont have any appetite, i never feel like eating, i only eat cause my stomach tells me I must. What can I do?
