I am going to admit something here that I've only ever discussed with my closest friend before.
I have been known to do the same. Also to go and deliberately make myself sick on a night out if I feel I'm getting too drunk too quick. I have never done it with the purpose of removing the calories from my system, but when I feel uncomfortably full (a la the Romans which have been previously discussed) and it made me feel better.
This had been going on for a few years now. My skin is awful, my nails are brittle, my teeth are in bad condition. I now feel queasy if I get too full and it takes a lot less than it used to for me to be sick (unforced). And at its worst I went through a stage of this being once a fortnight at most. That's all it takes for it to be a problem to your health.
My SIL and my best friend are, as they say, bulemics in remission. Neither would ever claim to have recovered. I knew for a lot of years that bestie was bulemic. She thought nobody knew. But even just spending 2 days a week at uni with her, I knew. Therefore when I realised that I was starting to show those traits I'd seen in her, I spoke to her about it. She is also a very highly qualified professional person who thought she was in complete control. She told me it started out as 'making good sense' and what harm was it if she occasionally did that. Later on she realised it had taken over her life and she was starting to look at food with a view to how hard it was to bring back up. She had been doing it 'occasionally' for years and bam! suddenly that was it, almost daily and almost every meal. She told me this in order to help me kick it into touch before it got hold of me.
She gave me the kick up the arse I needed to actually think about it. And do you know what? Of course she was right. More than anything, as much as you may feel in control, why would you deliberately put yourself in harms way. Would you shag around with random men you'd just met without a condom? No, because you put yourself at risk of STDs. So why would you make yourself sick after food, when it puts you at risk causing lasting physical damage and health issues, just to save on calories which you could actually go and burn off like most normal people do
Why am I telling you this? Because I know how easy it is to believe it isn't a problem. And I know that whilst it has the potential to develop into a serious eating disorder, you have found a way to rationalise it in your head. However, It is wrong . No matter what excuses you give yourself for it, even if those excuses are as lame and woolly as you're sure everyone does it and of course you're in control (you're not, by the way), it's a very slippery slope and it takes very little for you to slide down it covered in your own vomit.
All anyone has done on this thread is give you advice. Your original post did not ask for advice, just confirmation that EVERYONE did it, which as has been pointed out is not the case. Yes, more people probably do it than will admit to it, but that doesn't make it normal or right. More people probably take drugs than would admit it, but does that make it right/acceptable?
Please, OP, just think about it. People's responses here are to try to help you, whether you think you need help or not.
