I lost the instructions and warnings on how to apply the Hypercare solution and I'm not sure I did it right. I just squeezed some onto my hand and rubbed it all over my armpits. Also, it's itching ALOT and I fear I'll have some trouble sleeping! PLEASE help me with this! Would taking an antihistamine help the itching (they have helped when I have had itchiness related to allergies).THIS IS DRIVING ME CRAZY!!! I really want to stop sweating, but right now I don't know if the uncomfortableness is even worth it??
