Seroquel Side Effects - Anyone Else Experienced This?

recently got my dosage upped and it caused me to get extremely high to the point of not knowing where i was or what was going on and having to manually breathe basically. it made me freak out basically and then sedated me for 13 hours once i got less high. i had no other substances in my system other than lamictal (the other medication i take). i have had a lot of brain trauma and accidental damage from drugs as well (recreational), which has lead to me being so unbelievably reactive to any medication and basically made all side effects too unbearable and unlivable before any medication seems to help. the dosage i got upped to was 100. my psychiatrist said the average person who takes seroquel takes about 300 a day. has anyone else had side effects like mine with seroquel? thank you for any feedback <3
