I've been on 20mgs now for 5 days and feel like death. I came home from hospital yesterday following blood transfusion for low blood count and wasn't too bad while there. Now I'm home I'm a wreck. Spend the day wandering from the bedroom to the bathroom as I have constant trots. I had a bad anxiety attack this morning and spent ages sweating like the proverbial. Every time I take my tablet I feel dreadful sweats about half an hour later and I ache all over. I actually slept for 4 hours last night but hadn't for 5 nights prior to this so am dreading tonight and spending the time wandering the house. I can't concentrate to read a book or watch TV for long. How long will this last??? All replies welcome. Cathy
