No Headache  !!!
Best thing I've ever taken for that added support in the bedroom and one lozenge lasted me around 3 to 4 days. 4th day it was starting to wear off. But I think it's best thing for me and my situation.  No problem  keeping it up and finishing and ready to go again in less than 10 minutes. I just wish you got more for what you pay for them. Other than that I'm 100% satisfied.
