Hello, I m a single, 58 year old woman. Recently I have started to put on a lot of weight. I am on several medications. I take Simvistatin and Sertraline in the morning because I read where they can cause insomnia. I take Omeperazole in the afternoon, and in the evening I take Clonozopam, Zolipiden and Levothyroxin. I m wondering if my weight gain is due to any of these drugs or the way I am taking them. I walk a lot and do a lot of yard work, heavy yard work. I am 5 3 and weigh 160 lbs and I feel awful. Do you see something I am doing wrong? Could bottled water add weight with the Potassium Sulfate and Potassium Carbonate and the Potassium Chloride they put in the water?
