I would go for it! But, I would also advocate a little on the training if you feel it's not enough. We do a lot of detoxing where I work and it's not so difficult. A lot of CIWA's, meds, support, and sleep is what I find so far. I watch my detoxing pts closely because most have been through so much and it can be rough for them and on you. Many are not always nice, some are lost, some are scared, some are just alone, a few are not ready.
My place of employment deals with more than just detoxing. For my detoxing pts though; I start with report to get a feel for where they are at, when the next CIWA is due, food and fluid intake, labs, etc. I then physically lay eyes on each one, listen to heart, lungs, bowels, ask about pain, cravings, AVH (auditory/visual hallucinations), SI (suicidal ideation). Above all else, I care, I listen, I don't give lip service. I change their linens when they get up because a fresh bed makes me feel better when I'm not well. Offer fluids, extra blankets, whatever they might need. Some have no home to return to because they've burned so many bridges. Many seem to want to be left alone that first day or three. Most of my pts will watch the way I interact with other pts. Not sure why, but I have a feeling they are sizing me up to see if I do care because after a day or two they open up to me pretty well.
Good luck in whatever you decide! I hope this helps a bit.
