One 300mg and Done, Am I a Candidate?

Got my 300mg first shot 12 days ago.

Feel fine. Just tired and sorta numb. No withdrawal.

Was on 6 to 8mg subs for 5.5 months.

*Do I need more shots? What did your doc tell you? *

I’m low risk patient, not risk for relapse or death. Just got the shot to taper off completely.
