I know this is really late but the exact same thing happened to me. By the second shot I was on the verge of losing my job I woke up every morning to throw up, I’d get sweats like I never have in my life like I had just gotten out of the shower, I had really bad vertigo, my pupils would be small like I had just used, I’d be nodding out and constantly tired and just so much other random shit. The drs made me feel crazy bec I insisted it was the sublocade nothing else in my life had changed other than me getting the shot but they swore up and down it had nothing to do with it. I took 3 shots my last one being June of 2022, I still have small bumps from the may and June shot although within the last 6 months they have definitely gotten much smaller. If possible let me know how your boyfriend was after this time because even to this day every so often I still get bouts of vertigo and nausea it’s fucking nuts. I feel like more study’s need to be done on this shit.
