Morning
"You've been posting morning boners every day now for a long time. What's the significance?"
Waking on a very consistent basis without a hard-on is a sign that something is wrong, somewhere. If you have trouble getting hard on demand, don't go running to a doctor asking for boner pills --- especially from one of the online places. They can't do a physical exam and get to the bottom of the issue. They'll ask a few questions and send the meds. They're treating the symptom - not the underlying condition.
Never take morning wood for granted. That is one of the most important erections of your day. Your cock is talking to you --- pay attention. You are at your most relaxed mental state, Testosterone is topped off, and you should be waking up with a good, solid boner the vast majority of the time.
