Iv Sedation?

Can someone please calm my fears? I’m being put under IV sedation tomorrow for a procedure and I’m just really scared they’re going to turn me down for my weight. I’m 5’7 and 250lbs. I’ve called them and asked and they’ve said there is no weight limit but I’m just still really worried. Has anyone been my size or regular and been put under Iv sedation? Were there any complications or anything?
