Treatment after chemo

Hi, Would like to know how soon after chemo the 'other' medications start? I'm now counting down to my last Taxotere treatment and to be honest I've only focused on getting through the chemo, not what happens next. Do the medications start straight away? I need to do heaps more research but from what I've read so far it seems that Tamoxifen is the drug of choice. And the side effects can be pretty shitty. I was looking forward to not feeling like total crap all the time but I now doubt I will ever have that again. Anyway :/ Any info, tips etc would be much appreciated :)
