Is there something that could cure excessive sweating quickly ? like a certain medication or even food or anything ?

Hyperhidrosis: This has many possible causes, and often the cause is not found; there's probably a big genetic component. There are a variety of approaches to treating the problem if the underlying cause cannot be addressed. Dermatologists see this all the time and have equipment that may help. http://www.nlm.nih.gov/medlineplus/ency/article/007259.htm or the self-help group http://www.Sweathelp.Org/en/.
