I gained 30lbs taking Lexapro and Serequel. I am now only taking the Serequel for sleep. I have been dieting. I have been doing a diet consuming protein and only 800 calories a day. I am 5'8. I went from 150-180 in a matter of months. While doing this diet I have only lost about 2-3 lbs and I have been doing it for 6 weeks! I am frustrated. I am wondering if the Serequel is preventing me from losing the weight. I am working out 3 times a week cardio and a power weight class at the gym. I am not putting the food into me so I don't understand? Anyone else experiencing this problem? I have tried to stop taking the Serequel for the past 2 nights and I have not slept. I am feeling tired and irritable... I want to lose the weight but I need sleep.
