It certainly could have been a crimp of sorts, or blockage (or perhaps a big ol piece of poo). So tonight, try the lax again but milder. You can steep it for a shorter time or reuse the tea bag you used last night and steep normally. You may also opt for a nice enema. Get everything ready including your scents, visuals, a nice magazine and soft music (oh, and lube *smile) and give your colon a nice rinsing from *that* end. If you don't happen to have an enema bag, Walgreens has them for about 9 bucks. Add a drop of peppermint oil to help alleviate any potential cramping.
