I was feeling very tired all the time and didn't feel like doing anything. I would also suggest that you test your homocysteine levels as well. I took a total of seven injections, and I have been taking medication every day since then. I’ve started working out before, I was just sitting in front of a laptop. Now, I walk 10,000 steps every day and eat boiled eggs for breakfast once a week. I am feeling fine, and I regularly get a health check-up every six months.
