Anyone had an elective or planning on having one?

R
Just looking for a bit of advice as I'm planning an elective. His due date is the 21st Feb and booking the section this Monday! 
Can anyone let me know if the medication they give you during or after the section makes your head feel funny at all? I hate taking anything that makes me feel out of control as it will trigger my anxiety. Just wondering about other people's experiences as a nervous FTM! 
(There are medical reasons for my choice as well)
