Oh god, don't do it.
In all honesty, if you're taking it back to back and know you'll be OK with crying and dry heaving all the time due to anxiety, do it. (I'm being facetious, but it's rough! Seriously, OChem is something that I've realized you have to let sink in, and summer sometimes just moves way too fast for that.) That being said, if OChem 1 and 2 are going to be back to back throughout the summer, give it a shot (if you don't care about getting a break this summer.) However, I took one semester of OChem over the summer and then hated myself because of the burnout the next semester. I'm lucky my program has a generous drop deadline, or else a 'W' would have been on my transcript.
I'm currently a post-bacc, and the pace was rough on many of my classmates-- the majority of us entering the 2nd semester in the fall felt the burnout, and this accelerated semester convinced our professor to just not do a 6 week summer course in OChem ever again. My 19 year old cousin (also pre-med) took it at the same time and when I would come home to visit, we would sit, study together and mostly cry and eat our feelings. (I wish I was joking...)
If you're going to do this: Don't. Fall. Behind. Do all the homework, go to your professor's office hours constantly-- for every course credit hour, multiply that by 3, and that's how much you should be studying for that class at least per week. Good luck if you decide to take it.
