I have been taking benadryl as just a way to relax and get my mind off of my life. However the way it makes me feel sucks. Just last night I took a total of 400mg. It makes my RLS  worse at night, and I always seem to realize I wake up ever half an hour. This morning I didn't even realize I went to bed. I had a bottle of 100 - 25mg, and it's almost gone. I realized I need to see a doctor. All the pills gave me a kidney infection.DO NOT JUST TAKE IT. ASK UR DOCTOR FIRST
