Is it normal to feel lightheaded like this(of course not)
OK! So this has happened to me quite a bit and frequentlyish. I smoke every single day. I have been for 4 years and all of a sudden 3 months ago maybe this started happening. It'd always be when I've already been standing for a good 20 mins or more. BUT this HAS occurred while I was already seated. I would feel the lightheadedness, following the black distorting vision and muffled hearing. And an excessive amount of sweating. Like full on cold sweat going on. My legs would begin to feel like jello if I continue to stand and eventually I would collapse. I'd always have to be sitting and resting my head in order to relieve myself. This has been scaring the hell out of me for awhile and I was hoping so bad that I didn't have to quit smoking. I was starting to think it was from cigs but I also am really bad at eating needed meals daily and Pssh hardly any water a day. So would everyone else agree it's just because I don't eat and drink water? Or could it be more serious? That's all I'm trying to figure out
