... lost 20 lbs. Lot of vomiting, diarea, and tasting smelling a very caustic taste the whole time I was taking it and for 8 days these symptoms have continued after stopping the medication. I finally had thought to open a capsule and smell it and it smells like the exact fast and smell of a caustic acid that I have been smelling and tasting. Is this how it should smell? And if f so how long does it take to for these side effects to go away?
