Maybe it's just me

So I was previously taking brello with B6 before I decided to order 1 month of ProRx through refills. I was taking 15mg from brello and decided to take 12.5mg for my first shot of ProRx because I recalled someone saying ProRx was strong. All was fairly good but one day I didn't eat anything for like 24 hours (I was extremely busy and didn't really think about it) but appetite suppression and everything else was good. Well I took my 2nd ProRx shot Tuesday at 12.5mg and I'm again experiencing eating less in a 24 hour period and when I do eat, I get full quick and almost nauseous. I'm trying to decide if I should go down in dose again to 10mg. I'm not sure if dropping from 15mg to 10mg within a few weeks is bad. Maybe my tummy is off in general, but I don't wanna drop too low and start gaining if that makes sense. I'm 5lbs from goal and I don't wanna gain being so close. (I might go another 5 after losing 5 more lbs. I am at my first goal of hitting normal BMI of 155lbs. I want to go to 150 and see what I look like. I still have some pudginess but don't want to push it too far and look sickly. I'm still trying to get used to this weight in the first place since I haven't weighed this much in 20 years)

Any suggestions? I just know not eating and barely eating is bad and can cause weight loss to stop, but I don't know if dropping down quickly is also the best option either.
