... days (25 mg. daily) and 40 mg of dex. on Monday of each week. Some days are okay however it seems that by the Wednesday after taking the Dex, I am so fatigued that I can hardly make it through a day of work. Can anyone make any recommendations on energy boosters? Multiple Myeloma makes you tired anyway and with the Revlimid, it adds to the tiredness. Any suggestions would be greatly appreciated
