high blood pressure
"On 100mg.   My BP was around 147/95 for several years.  The odd thing is I'm fairly fit.   I got off big cardio a few years back and just lifted weights 5-6 days a week.   Yeah I got big, but I knew things were not right, BP was HIGH.   Got onto Losartan, first few days on 100mg...I almost passed out, sweated profusely, was dizzy, and really shouldn't have been driving.   I've switched it up to 50mg morn, and 50mg night.   Now my BP is back up high, and I'm just not seeing results (I'm back on 30 mins cardio, 30 mins weights daily, sometimes double that.    First month this Losartan really messed me up...couldn't concentrate, personality kind of disappeared for a while.  Back level now...but if I get even a little bit dehydrated, I feel faint"
