I take Sertraline, Abilify and Clonazapam for depression, anxiety and ocd. Presently, I'm dealing with a major problem with caffeine consumption that's starting to ruin my life. I know that sounds strange, but it's true. I drink 6-8 20-ounce Diet Dr. Peppers a day, every day. I don't like how it makes me feel, but I can't stop drinking it; I'm obsessed with it and think about it all the time. I have heard that caffeine interferes with antidepressants - not just because it makes you jittery, but that it really interferes with the absorption process and makes your medication ineffective or less effective. I feel gross, physically and mentally. I have a therapist and she is working with me to get off the soda, but it's not working currently. I used to be slender and attractive, now I sort of look like I'm pregnant (I'm not.). I feel sick during the work day and I'm losing my productivity (I'm in sales.). I don't feel like eating when I drink a lot of soda. Does anyone have any advice or comments? I would appreciate them!!!
