I too only take them occasionally ,but as I know they work fast it's like a security blanket to know they are there and that's half the battle you will be fine Mrs Bennett on 2 mg once or twice a day ,if it's a really bad spell you are having don't be afraid to use them for a few days your body will tell you when you don't need them and that you can once again get it all under control ,just be aware not to use continuously for days on end . Most gp only prescribe 14 at a time and I to still have 4 left from script beg. November. Have a great time x
