Hi, I Really Love Using My Corset And Cinche Because

Hi, I really love using my corset and cinche because it makes me look great but I've noticed that I start to get a headache towards the end of my work day. My cousin suggested just taking it off until my headache subsides but still continuing with my goals. What do you think? I already exercise 3-5 times a week (at least 5 miles + other exercises to tone) but I just can't get that coveted hour glass figure. This is the only thing that seems to actually work. Within the last week I've witnessed a noticeable difference in my waist. I don't want to stop corseting but I can't bare these headaches. Any suggestions?
