today I dove in 2 types of climateswith my new wetsuit one was like 65F then the other was about 78F.When I dove them I was wearing my 3.5mm opencell suit.OK so I dont know what happened to me but I got real sick feeling like nauseous and I couldnt breathe.after I took off the hood portion I was cold but fine....Am I just uncomfortable with a suit or can you actually get like heat stroke in one of those?
