Management of my appetite was the biggest challenge, so the medication [Wegovy] has really just been game-changing. I've been trying to lose weight for 14 years. As soon as I knew about this medication from my research, I ordered it the same night I found out it was available.
I had tried every diet under the sun. I finally plucked up the courage… and it has changed my life. I am happier, more confident, full of energy and able to run around after my children for longer. [It] has drastically improved my physical, emotional and mental health.
I was starting to get a pain in my knee which seems to have decreased a lot since losing the weight. I don't get any more back pain. It's made me a lot more confident within myself. I actually want to go out and do things. I want to go clothes shopping. I want to enjoy things with my kids.
I can do more. I feel more energetic. I can play more with my kids, whereas before I was restricted. It's mostly the breathlessness, the being slow, being out of breath, feeling heavy, not being able to put my clothes on properly because they were too tight. It's been a brilliant experience with MedExpress.
I used to hide away in oversized clothes, just trying to feel comfortable—but I had no confidence. Now, I'm fitting back into clothes I haven't worn in years, and I actually enjoy getting dressed in the morning. I feel happier, more confident, and like I'm finally showing up as myself.
It's making me more happy about myself. I'm feeling more confident. I'm not hiding. If my friend invites me for a coffee, I won't say no anymore. I'm dressing-up! I'm taking care of myself now. I feel more happy every day. I'm more talkative. I'm going to more family events.
