In reply to Flakes:
Er yes. Be careful. I started again a few years back after a long layoff. I found I had no endurance but could still remember how to do moves. So anything pumpy was a major challenge, but I was quickly back on vertical/slabby 6b's, thinking "ok, I know how to do these". And acquired my first ever finger pulley tear within three months of starting to train again. Oops. Swallow your pride, take your time, don't be in too much a hurry to re-live former glory.
More pride-swallowing might be useful in the direction of belaying technique. You don't say how many years you've been away, but in my case it was well over ten, and I discovered that I had a lot to re-learn in terms of modern sport belaying technique. My old skool, trad belayer, "lock the plate and hang on for grim death" approach to catching falls was unlikely to kill anybody, but wasn't necessarily particularly relaxing for the belayee. I had to accept that I had to change my ways and ask my new climbing partners for some tips. I even did a course.
That all sounds very negative. It's great, I'm delighted to be back. Have fun.
