Yesterday while exercising I felt very weak, way beyond normal. Not muscular week, but physically. For example, I felt like I could jump a certain height, but when I actually attempted the jump I barely went off the ground. I didn t think much of it and thought it was just an off day. But now, I woke up and ate breakfast only to find myself feeling dizzy, weak, somewhat nauseous, and having a strong bitter taste in my mouth making me swallow often.
