Maintenance treatment post ASCT for myeloma

Has anyone with Myeloma post ASCT been taking lenalidomide for maintenance? How long have you been on it, at what dose and any bad side effects so far? I chose to take velcade for maintenance but I'm wondering if lenalidomide might be better? I chose velcade because I didnt like that lenalidomide has risks of secondary malignancies, causes fatigue due to neutropenia and may cause skin rashes .
