Puffiness under eyes symptoms and conditions

I took Lisinopril for 3 months. Symptoms gradually got worse: eyes watered, nose dripped, ears itched, puffiness under eyes, hair loss, tired all the time, body was very tense, night sweats, couldn't sleep well, and started having sharp pains like pin pricks. The doctor said to stop Lisinopril and switch to Cozaar (for Losartan). I didn't want to start another medication until I got this out of my system, so I stopped Lisinopril 4 days ago. My symptoms started to subside in about 3 days, but then I started to get horrible cramps behind my thighs. For 2 days now the pain keeps me awake at night...I can't get comfortable. At 11:00 p.m. tonight I had to take 1 Lisinopril to "wean" off this horrible drug. I don't have hypertension, but was recently diagnosed with type 2 diabetes--so the medicine is supposed to "protect" my kidneys. Does anyone know whether Cozaar is any better? I hate taking meds!
