I think everyone needs to focus on 3 things when fatigued n having heart palpitations dental related parasites or heavy metal as I am in same boat I highly suggest u look at dental issues I'm heading to tijuana mexico for cheap good dental it's those infected root canals that cause silent inflammation and those cavitation am learning the mouth causes many problems I'm going all the way to tijuana to take care of infected root canal and mercury removal screw all this fatigue I will knock this out first then do parasite cleanse possibly metal detoxing too start with the mouth then work on the gut as they are both connected
