I’m thinking about trying midol for the first time. I’m 16. I like how the complete midol promises relief from all the symptoms, but some people are saying that the caffeine makes them jittery/unable to sleep. Would I be better off getting the teen version? My main problems are lower back pain, cramps, bloating, and sometimes headache. I’m worried that the caffeine will make me crazy. What do you think? Experiences?
