I used fitfirst for two weeks, but got no results so I was advised to switch to another medication called Harva and I have been using it for the past 5 days. The pills are supposed to be all natural slimming pills that control the appetite and help in fat burning. Starting a week ago, I started experiencing unusual feelings. I sometimes feel disoriented, I get severe mood swings and depression, I sometimes feel as if I am not present in the particular place or among the people I am with! And my reactions are a bit foreign to me, including that I suddenly could cry or wake up in the morning and start crying! Do these actions have anything to do with me using the diet pills?
