the main thing is that most side effects are manageable, cold -easy, wrap up! lightheaded -add some salt. also nearly everything is helped by drinking more water -except needing to wee more.. but thats unavoided, does settle down after a while.
doing lighterlife my hair started to fall out but once I started eating again, and it settled down and I still have a full and thick mane, I also was bleaching my hair at the time which wont have helped. (i know it wasnt the sole cause as ive bleached hair before)
you need to just take it easy as you settle into it, hot baths, relax in the evenings, early nights -you sleep like a log once you stop trying to knaw your bedcovers. oh and I had plenty of dreams about being at buffets etc and waking up drooling with aching jaw -wouldnt be surprised if I was a pillow down!
id also sleep next to some water and prepare to run to the loo first thing in the morning whilst drinking water...
all good fun in the name of not being fat! worth it !
