Overdose symptoms can include: chest pain, dizziness or an irregular heartbeat. Actually since you do have tingling in your arms, it is advisable to be seen by your doctor or be seen in the ER, as this is the recommendation from the drug manufacturer for Viagra.
It takes about 5 hours for your body to break down this drug. So do wait at least 24 hours before taking anymore. Also, eating a high fat meal just prior to taking Viagra can greatly decrease its effectiveness.
