I’ve found that trying a few different options can help you see which works best for your body. Many people have different reactions to these medications, but generally, Viagra starts working in about 30-60 minutes. Cialis can take about the same amount of time, but it often lasts longer, sometimes up to 36 hours, which some prefer for spontaneity. Levitra is a bit similar to Viagra regarding onset time. As for side effects, some experience headaches or flushing, but it’s not the same for everyone. It’s worth discussing any health conditions you have with your doctor, as they might influence which medication is best for you. Trying them and keeping your doctor in the loop about your experiences can help you find the right fit.
