Levitra
"Many men complain of mild stuffiness, headaches, nausea, palpitations, etc.
Advice: Try lower doses until the effect isn't enough.
Example: My Doc gave me a few 20mg Levitra to try out.  Did that. Love it but:
WHOA!  Way too strong for me. Stuffy nose, mild pulse racing, mild headache.
1. Cut dose by half, still a bit much for me, as side effects persisted to some degree.
2. Cut dose in half again, JUST RIGHT! Side effects almost un-noticible.

Same with Vardenifil. Sometimes all I need is a small 'chip' of it to get'er done. Dissolve under tongue. "
