I have been gaining weight fast. Ten pounds in a few months. I use to exercise 3 to 4 times a week. When I do now I end up getting shaky, I sweat profusely, feel sick to stomach, feel like I m going to pass out, this sometimes happens even when not working out. I m tired all the time, no energy stomach always bloated. I have gone from 169 to 181 in about 6 months.
