I have used Advil for a long time. I do not take them often, but I do when I have a headache or something minor like that. They always seem to make my headaches go away. They do not work as fast as some other things I have taken for a headache, but they do work really well when they kick in. I usually keep a travel size bottle of these in my purse so I have them just in case I need them when I am on the go. I love that they are affordable also. I have found these for very decent prices in my local drug store. My dad prefers Advil to any other pain reliever. He has a very physically demanding job and takes these pretty often. He says they take aches away even after some of the hardest days he has at work. I would recommend these to people for headaches, as that is primarily what I have used them for. So I cannot vouch for whether or not if they work for other aches. Effectiveness Advil works for my headaches, but sometimes it does not seem to last long enough. Ease of Use These pills are a decent size so they are easy to swallow. Immediacy I feel like Advil works pretty quick.
