Molly nervousness help

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.

My group all rolled together last night and are planning on doing other stuff tonight so I won’t be alone but not rolling with them. I’m thinking of just doing 100mg and maybe 50mg redose crystal in caps. I’m just worried about how bad the come up is cause is it really that bad or was it just cause I was dehydrated and didn’t know there was a come up last time and just thought I took too much?
