Day 4– weight question!!

Day 4 on this med.. its helped my anxiety alot so far . I take it in the morning with breakfast. So far all ive had is migraines and some brain fog.

Today i woke up a little anxious. Constantly fidgetting.. not sure if its my adhd flaring up.

Now my question is .. I've lost some weight bc of the anxiety and lack of appetite prior to starting this. My worry is this medication making me lose weight even more. Anyone knows how to maintain weight with this medication making?? Or how to gain it back? I mean i am hungry but not like EXTREME
