I have tried Cialis and the side effects from it are more difficult, so I'm hoping to be able to make Viagra work. I did use the 100 mg dose and will try reducing it in half and see how effective that is. Just wondering if anyone else has had the issue and resolved it or reduced it with over-the-counter or other methods. One person said that it depended on how much food he had in his stomach but was not clear whether more food or less food helped. Thank you
