I had abused diuretics for about a year. 160 mgs Lasix per day, obtained online without a prescription. Several days ago (4), I gave them up, cold turkey. The rebound edema is worse than I ever would have dreamed, and getting even worse by the day. Is this medically dangerous? How long will it last? Is there anything I can do (drink lots of fluids, e.g.) to provide relief? I am too ashamed to ask my doctor. Thank you for your help.
