I have 5mg oxybutynin chloride tablets for excessive sweating all over the body and it definatley works but I'm finding the side effects really tough such as dry mouth that gives me soul ulcers when I exercise in particularly. Can I just use it for social occasions like dinner, festival, client meetings when I know I'm going to be around people? Also can you consume moderate alcohol on them? I found they worked within a day is this normal timing for it to take effect?
