Anyone at a standstill

Anyone at a standstill? I have been on Zep for 4 months and started off strong, I increased to 5mg for 3 mos and after staying the same weight for a month, I increased to 7.5 and on my third dose now. Not feeling the same as when I started. I feel full at times, but I don't feel anything else. I'm not looking for medical advice, just wondering if people felt a longer stall and if it eventually changed. I am having a hard time trying to stay on lower calories, but food noise is there and so are cravings. I am currently 50 lbs into my total weight loss journey, but only 25 lbs on Zep in 4 months and most of that was in the first two months.
