We were actually booked to snorkel, but since everyone on the boat was diving and we had to "share" the day, they persuaded us to switch to diving, which we unfortunately agreed to (they even wanted us to pay extra for doing them a favour, which I thankfully said no to). When I got in the water, I was hyperventilating and was getting worried, and told the instructor I couldn't breathe...but he didn't really listen to me and kind of just made me go in anyway. I have to admit, I saw some very beautiful scenery whilst under there, but as soon as I got out of the water something went completely wrong. I started projectile vomiting and feeling like I was dying- everyone was saying it was sea sicknesses ( I've been on many boats and in much more violent waters, and never suffered before, and kept telling them that it wasn't sea sicknesses, otherwise I would've been suffering before we got to the diving spot, as it took a little while to get there, but once again, they just wouldn't listen). I told them I wanted to get to land because I was feeling too sick to cope, or to the island we paid to go to (Giftun island) and they told me no, and that I would have to wait until we arrived to the second diving spot and that it would take another 1-2 hours before we headed back. Thankfully I managed to lie on my stomach after completely emptying it out and got better towards the last 20 min of the journey back, once again proving it was not sea sicknesses. As soon as I got home, I contacted a reliable doctor, and he told me I risked my life, as I could've passed out under water due to CO2. Do yourself a favour, if you don't have a PADI certification and have never done diving before, do not do this here in Hurghada. Not worth the life risk, and these people couldn't care less about your well-being. Oh, and they were also trying to get me to say I didn't have asthma on the medical information sheet, which I find a bit dodgy, and refused to agree to this. Please be safe and please think twice about doing your first dive with anyone in Hurghada. It's not worth the risk.
