I get REALLY bad period pains and I use Anadin Extra when it really kicks in and Ibuprofen just doesn't touch it. I am Pretty sure I'd have been in prison years ago for man slaughter if it wasn't for those tablets making the pain a little less so my sassy ass doesn't b-fit too much & rage at the world for no reason other than my hair doesn't smell like my shampoo for as long as I hoped even though the bottle costs £435367589ect.. and the cheap £1 bottle of shampoo leaves your hair smelling nicer for longer and that's total bs in itself. I digress, Great Product and it works SO WELL! I have also used this product for migraines and back ache, it does it's job very well, relieving pain fast and the pain relief lasts longer than any other over the counter pain relief I have tried before.
