i tried overdosing on a combination of venlafaxine and sertralin last month. i believe i took about 4.5g of venlafaxine and 12.25g of sertralin while also using weed as an antiemetic at 72kg, and clearly i've survived, but i feel like i wouldn't if my mother wouldn't've found out before i could even pass out. i ended up having a seizure in the ambulance and woke up 4 hours later in the hospital with my stomach pumped out and i remember being really shaky and unable to focus. i was also really weak and it was a struggle for me to even hold my phone. i remember struggling to walk almost a week after i got hospitalized.
in conclusion, i have no idea if it would actually kill me but the aftermath was really painful to get through.
