I know an OR nurse and she said that the rule of thumb is one week for each day you are hospitalized after having surgery. So I think that 2 weeks may be coming up a little short as well. Everybody recovers at different rates so I would discuss this with your boss/surgeon a little bit more so that you will allow for proper coverage at the job.
In terms of what to expect....there are very few I recall going through the reversal....I tend to agree with what Renata describes that most of it will be the readjustment of the colon working at full capacity once again which will involve introducing foods at a slower rate until it gets back on track.
As far as over all recuperation time I would imagine that it would be less than when you went in the frist time....did the surgeon indicate if he was going to reattach through the stoma site or is there more opening up involved??? And will he be doing it laproscopically???
I hope all goes well and know that we are here for you wishing you a speedy recovery.
