Sorry you are needing the scopes, hoping all is well and that there are no other issues added to your plate afterwards.
I've tapered off Gaba many times without any issues. If I remember correctly you haven't been on it that long so that should ease the side effects of tapering. Remember though when you ramp back up any of the side effects you had the first time will likely reoccur.
Good luck!
PS., ditto what Vrae said about "not borrowing trouble". I know needle sticks can be scary but the actual cases of spread from this is very, very small. Worrying will only heighten your nervous system and increase pain overall. Think positive and believe all will be okay.
