Hi BR. Congrats on the 150 days. That's a lot of sober time, and you probably felt like you could take on the challenge.
I drank at home, which keeps me away from "party/club temptation" but isolation can be bad too. Maybe best to stay out of drinking venues for a while. I don't do AA and wish I had more friends. Sounds like you have plenty though. Do they know about your sobriety? Respect it? If so, see if they can respect the boundaries you set when all together.
After my several 'slips' I didn't go back to day one. My accumulated sober time meant more to me than a few bad mistakes.
Get back on track and stick around!
