Wow . Those fade slooooow <| sep |> I am puzzled by how they would even treat bacteremia with coliform bacteria . But , on reflection , I imagine that such infections would be so common , at least on a small scale , that the immune system would be tailored to fight it . <| sep |> I ' m normally against recommending mass gainers but I was very underweight when I started and I used a mass gainer when to help get calories in . It ' s better to get calories from food but try a mass gainer shake recipe until you find one you enjoy . My beginner shake was chocolate mass gainer from ON , milk , banana , peanut butter , Nutella , honey , yogurt , oats , and tbsp . of olive oil . It tasted amazing so it was enjoyable to drink and I didn ' t feel so nauseous from it . It helped me build a routine of shakes everyday and increased my food intake . In the beginning it could take me a long while like an hour to finish a shake but after awhile I could down one in few minutes and be hungry almost right away . After a couple months I switched to a protein powder and started eating more regular food
