Growing up, I faced numerous challenges that left me feeling lonely, insecure, and anxious. These early experiences likely contributed to the severe stress, migraines, mood swings, panic, depression, and sleep disturbances I've struggled with for the last ten years. On two occasions, my mental health struggles were so intense that I needed psychiatric care.

Last year, in the spring of 2024, I embarked on a journey to improve my well-being by incorporating two products into my routine: CarboHaler and Cardisuit. I started using Cardisuit for 15 minutes and CarboHaler for 8 minutes at 3.5%, five times a week. To my astonishment, on the second night, I slept for 14 hours straight—a significant improvement from the 2-3 hours of sleep I was accustomed to.

Additionally, the nightmares that had haunted me since childhood—intensified further after a recent right hemicolectomy surgery— dissipated within two days. My dreams are now filled with happiness. I wake up smiling, without fear, and my severe morning migraines are completely gone.

After Two Weeks, I Stopped Taking My Antidepressants

After two weeks of consistent use, I felt confident enough to stop taking my antidepressants. My Apple Watch data revealed that my deep sleep increased from just 2 minutes to 40 minutes per night. As my sleep quality improved, I noticed a corresponding increase in energy, a greater sense of happiness, and a significant reduction in panic and anxiety. My mood became more stable, and I felt a sense of inner calm that I hadn't experienced in years.

Testing Life Without CO2 Therapy

After four weeks, I stopped with the CO2 therapy altogether. I wanted to see whether I could maintain my newfound mental and emotional health even without inhaling and absorbing extra CO2 through the skin.

For the next three weeks, I continued to feel happy, energetic, and sleep well, etc. But then something really stressful happened—something that took me completely out of my comfort zone—and my anxiety and stress went through the roof.

Not Afraid of the Traffic Anymore – I Even Bought My Own Car

BUT—it only lasted a day.

Normally, recovering from that kind of event would take a VERY long time. So what did I do? I reached for the CarboHaler, and it calmed me almost immediately. After that experience, I decided to resume using both the CarboHaler and Cardisuit again, about five and 2-3 times per week, respectively.

Four months later, in August 2024, I still hadn’t experienced a single relapse. Thanks to my calm mind, I started to perform better at work and was even promoted. To my husband's big surprise—since he didn’t even know I was taking lessons—I also got my driver's license.

Driving would have been completely unthinkable just six months earlier, before I started improving my CO2 tolerance. One of my biggest fears had been traffic. Where I live, in a suburb of Colombo, Sri Lanka, we don't have many red lights. Crossing the street has been one of my biggest fears, and it could easily take me 10-20 minutes to build up the confidence to cross the street. But the other day, I did something I never thought possible: I bought my own car!

Yet Another Stressful Time Was Relieved With CO2

Fast forward to February 2025. We started renovating our house. What was supposed to be a small renovation turned into a full-house overhaul when a wall unexpectedly collapsed.

We had to move out immediately and relocate to a tiny temporary place. Life became chaotic. I couldn’t continue my CO₂ therapy in that environment.

Despite the disruption, I felt calm and balanced for the first few weeks. But after four weeks of constant chaos, the old patterns returned. My nightmares came back. My resting pulse stayed between 100 and 105 around the clock. After three nights of almost no sleep, I decided to return to the CarboHaler.

That night, I slept for 16 hours straight, and after a few days, my resting pulse came down to 80–85.

A New Chapter of Calm and Confidence

I am profoundly grateful for the positive changes that CarboHaler and Cardisuit have brought into my life. These products have been instrumental in helping me find peace, regain balance, and live with confidence.

I never imagined I’d be the kind of person who drives confidently through Colombo traffic. But today, I am. Thanks to my increased CO2 tolerance, I’ve reclaimed my peace, my health, and my life.
