Tweeti had them out about 2 months ago. wasn't that bad. i had some gas goin for a while, it more or less just relaxed me..made me more tired than anything. then the doc came in with a couple vials and was like "ok, these are gonna knock you out" i said "ok" so he injected the first one...nothing, no big deal. then he injected the 2nd one, damn! lol. within a matter of maybe 10 seconds, i woke up an hour and a half later,lmao. i was pretty numb and a lil dissoriented when i woke up, but i wasn't swinin' or anything. i got home, watched tv (was hungry as phuck!) but toughed it out and took me 5mg of percs and felt a lil better. i kept passing out uncontrollabley from the shit they gave me in my IV and the perc,lol. i would just be sitting there and all the sudden start snoring. i'd wake myself up with my own snoring,lol. the percs helped for sure, had to get a refil a week later cuz my shit was still irritated. he was apprehensive about giving them to me, he said "you know, we're supposed to ween you off of these, right?" i said "look man, i'm no addict. i just need it for the pain, ibuprofen ain't doin shit!" so he gave me the refill. took about 3-4 weeks for my mouth to be fully functional. also, try and get the dissolvable stitches, that way you don't have to go back in there. thats what i had and within a week and a half or 2 weeks, they were gone.
also, if you wake up and your tongue is really sore, you probably stopped breathing. thats what happened to me. for about 2 months...yes months, after i had the procedure, my toungue would always get this tingly feeling and be painful and numb at the same time if that makes any sense. well i asked the doc about it and he told me i stopped breathing for about 20-30 seconds and my tounge kinda rigor mortised on him, so he was pressing down with his thumb and index finger something fierce to keep it from closing off my airway. thats why it hurt so bad for so long. even now when i brush my toungue while i brush my teeth, it still feels weird.
sorry for the long post and good luck! lol.
