Each of the ED drugs work a little differently. Viagra tends to give a very strong erection when taken properly but only last about 4 hours. It does not mean your erection will last 4 hours, it only means you will receive increased blood flow for that time period. Cialus works over a longer period of time, approximately 24 -36 hours, but usually does not give such a strong result. It seems to be good for guys that just need a little help. Levetra works more like Viagra but has different side effects and might be an option for guys that the other two drugs either are not effective for or cause undue side effects. It is the least popular of the three.
The important thing is these drugs have to be taken properly. If you are getting headaches from any of them, try reducing the dosage. Most guys can split the pills in half and achieve the results they want. The biggest problem with all of them is that the pills need to be taken on an empty stomach. If you have eaten, the drugs can take up to 3 hours before work. That can be a real waste of time if you are planning to have sex after a nice night out with dinner for example. They do make sublingual Viagra and Cialus that are not affected by whether you have eaten. They tend to work better and be more effective. You put the sublingual under your tongue and the medication is absorbed into the blood stream without going through the digestive tract. Sublinguals work in about 20 minutes whether you have eaten or not.

I would try the Viagra sublingual soft tabs first. In most cases, they solve the problem the best. I would only try the injectables as a last resort. They are much more evasive solution than just taking a pill. Sticking a needle in your dick is just a little more scary.
