My daughter was diagnosed with Dissociative attacks 3 years ago, she has been having them for 7years, we were originally told she was fainting. My question is, how long is too long, for her to be unconscious? Her longest to date is 1hr 50mins, she has just came round from a 50min one, she can be sick whilst out, and her body goes into spasms, she takes citalipram, but I don't think it helps at all. She has an appointment with consultant on thu. All answers appreciated.
