I might have that too.

When I tried asenapine, I received a mild-moderate antidepressant effect that lasted for about a week before it capitulated to my supremely stubborn brain. I like asenapine. I found it to be a very clean drug with respect to side effects, including sedation or brain-fog.

Last time I checked, I only found one inverse agonist at 5-HT2C, and that was sertindole (Serdolect). I tried it and had to quit due to extreme nasal congestion.
> However, I read one paper that said specifically that asenapine was a pure antagonist and not an inverse agonist at 5-HT2a receptors with little affinity for 5-HT2c receptors. Asenapine causes virtually no weight gain compared to the great amount of weight gain with olanzapine and clozapine.
