I registered disabled so they are allowing me to come in when I'm ready as I work shifts, but i keep hitting the sickness policy trigger which means I end up before the SMT who know I'm not taking the mick, but I can tell they're getting fed up, but not as fed up as me. I get them on my days off as well and leave me feeling awful for 24 hours after they've disappeared. Definitely worse over teh last 10 years, no medications work, terribly sick with them, speech affected, mobility affected, light/sound sensitivity, completely debilitated when I have them. At the end of my tether. I cannot predict them.
