I can only speak for myself and my experience. Recovery was not bad. I was extremely tired for about 4 months so I agree with the previous post that rest is essential. I remember binge watching Call the Midwife and a lot of shows I had on my list because I had NO energy. Just plan to have a lot of down time and take it easy. I read so much information that scared the crap out of me and none of it came true.
1. I never dumped or had food get stuck. Never puked (to this day)
2. I never got dehydrated. Water was not that hard to drink when I added limes or water additives. Hint water also went down very smoothly and I ordered several cases
3. I did go through a period of depression and most people do. You wonder what you did, how long will life be strange etc. Im about 1.5 years out and life seems really normal to me now. The only time I feel "altered" is when I eat at a BBQ or family event and I cant just have a hamburger and some sides. Its just the patty, cant really finish it and I cant have a bunch of beans and potato salad but other than that eating is pretty much the new normal
4. My hair did fall out more than usual but I never had major hair loss and it slowed down a little more than a year out
To sum up...dont be scared!! They tell you all the terrible things that could happen because they kinda have to but dont expect those things to happen. Keep a positive outlook and you'll do fine
