Started with 2 mg of Doxazosin with 5 mg of Tadalafil but take it right before I go to sleep and have had no problem whatsoever. The concern, and it rare, is that lowering BP so quickly can cause lightheadedness when one moves from a sitting to standing position (think head rush). It's why it's suggested to titrate the drug. Taking it before bed eliminates that from happening.
Upside to taking before sleep...morning wood is impressive.
Normal Doxazosin dosage for BP is 4 mg up to 8 mg. For the purposes of getting a good erection no more then 2 mg is really required but it's okay to test and see where your "zone" is.
I started taking 5 mg of Tadalafil every 12 hours now and I can get a decent erection on demand and sometimes not on demand LOL
