Muscle twitches and cramps can be due to a lack of electroylytes. You might want to get an electrolyte mix and also make sure you are getting a minimum of 8 80z. glasses of water a day, more if you can stand it. Many of the antifungals seem to have a diuretic effect and you could be dehydrated. I drink a mix in the summer, when I am working outside called, Emergen-C electrolyte mix, no sugar. Just a thought and hang in there!
