Pada, is your drug of choice alcohol?
Im 17 days sober today and sweat a lot when I first quit. It took... maybe a full two weeks to have that subside noticeably for me. The worst was at night... couldn't sleep, bad night sweats.
If I were you, I'd check online to see what types of meetings are going on tonight. Based on descriptions it's easy to pick meetings where you don't have to participate much. Also, you can always say "I'm going to pass tonight." or something along those lines if you do not want to share. I just did that the other day.
Good luck, stay strong!
