Excessive sweat and smell

Ari

I've noticed lately that my deodorant isn't doing the same job as it used to. I don't know if I've somehow become a sweatier person? I also noticed that I smell more now. I used to never be insecure about how I smelled but now I find myself checking if I smell 80% of the time. Has this happened to anyone else? What deodorants do you suggest?
