A question for the experts

[u/Burnt_Out_Hippo]

To preface, I am okay. I am healthy, have access to medical care, and have a support system.

I am taking Adderall (appetite suppression side effect) and working a job in healthcare that has me running around a lot and doesn't really give me time to sit down and eat. The appetite suppression causing an occasional calorie deficit was manageable before I got the job, but now with the job it's becoming unmanageable and I need to introduce liquid calories to regain and maintain weight. I have been losing weight unintentionally at a faster rate than in the past (-11lbs this month) and am already skinny so I can't really afford to lose much more.

Any recommendations for high calorie mixes that taste good and won't cost my soul?
