I am a just over two years out and I have gained 40 pounds back. After surgery I had no complications. Nothing made me sick, there was no food that I couldn't eat or that I couldn't tolerate. I did good for a little over a year then I hit a rough patch in life and went completely downhill. I was craving and eating sweets like it was nothing, I was drinking again and often, I quit taking my vitamins regularly. I was taken off of my depression and anxiety meds and put on Vyvanse. It seemed to be working for a while. The transition from my regular meds to Vyvanse happened right before I had surgery so of course, it helped me losing weight. I lost 114 pounds. Then all of a sudden my Vyvanse seemed to not be working anymore. Everyday was a struggle. I tried to get taken off of it a few times and my psychiatrist didn't think it was a good idea. I tried to take myself off of it and I quickly figured out that was not a good idea. I am so irritable most days. I have gotten to where its a struggle to even want to get up out of bed and do anything. I've had several people at work tell me i'm never happy. I'm always complaining or biting someone's head off. This is not me at all. I am generally a happy and fun person. People used to like being around me and now i'm pretty sure they don't. I finally took my myself off off of my Vyvanse (3 weeks without it) and struggled through it. My psychiatrist put my back on depression and anxiety meds last week so i'm hoping to be doing better soon. I've started back on how i'm supposed to eat today and have all of my vitamins. Has anybody else went through something like this or experiences irritability and unhappiness?
