I have a chronic pain condition and go regularly for procedures at hospital which they administer gas and air for pain prevention and it's bloody brilliant! I like that the pain disappears and the hazy feeling it gives me. I usually end up laughing and talking rubbish 😂I've had daily pain for twenty years now due to endometriosis and other gynaecological conditions. It's intense and nothing touches the pain. It's horrible. I'm desperate to get hold of Entonox for home use but it's obviously only available in medical settings for good reason. Can I get hold of any from abroad or somewhere? I'm desperate for the only thing that makes me feel better!
