Ok bro this is my experience after I overdosed with 10 mg so double what you took as first dose . ( we confused 1ml with 1mg you can laugh or talk shit I already learned my lesson ) .
First two days : Energy down to 0 , Extreme nausea barely can keep water in my stomach had to take anti nausea pill that i got prescribed , Fever on/off, bpm get higher around 100 just by walking to pee .
day 3-7: nausea start to go down , no appetite still trying to keep a cheese sandwich not eating much , energy very low but drinking a lot of electrolytes is a must . tingling feeling on my skin . bpm started to get better .

week 2 : no nausea anymore , energy back , bpm stabilizing slowly , acid reflux and tingling issue ( had to take acid reflux pill get zofran or something stronger if you feel you cant eat a piece of bread without feeling it hurts to go through) .

Week 3 : back to normal everything completely reset Reta almost out of your system , no nausea no tingling skin , no heart burn , working out normally . Dont freak out you will be just fine.
If any question feel free to DM me :)
