If you are taking 150g protein and you are taking 2500 Kcals you are getting too much fat and carbs. Drop the Kcals to 2000 ish like you stated. I would up protein to 175g-190g.
Clen can be rough. I’ve ran it a couple times and never gotten over 80 mcg. Make sure to keep plenty of water in your system or you will have cramps terribly
