I am so happy to hear that your surgery went well and that you're doing fine.
Don't hesitate to use the Gas-X strips, they were a life saver for me - really, really helped with the gaz. Also, don't be skimpy with the pain killers - if it hurts and you're within the prescripted limits, take it! Pain control is a very important part of the recovery process.
I don't remember how long I went without a BM but I remember that when they came back, they would be few and far between - maybe once every 3 days. That lasted for about 2 months. So, don't worry, this too shall pass
Take care and keep us posted!
