Nervous for some reason

Planning on rolling tonight and nervous about the come up out of nowhere. I did 130mg once in June and didn’t realize there was a come up, so I kinda panicked and drank a ton of water then felt fine after electrolytes so now I know to just chill and not over drink and have electrolytes. I also plan on using a supplement kit (rollkit). It’s gonna be in a large packed venue and just worried about overheating cause I get hot there sober too. Will taking propranolol help my nerves or should I just tell myself to chill and just drink enough water and dress light
