While I was taking Tenuate ( Diethylpropion), an anorectic, which now been discontinued, i had trouble sleeping.
It was 2005.
I went to a GP, was given Avanza 30mg.
Now I've been taking it for almost 7 yrs. I then was referred to a psychiatrist, he increased the dose to 90mg at night.
So far so good. But, compared to other antidepressants, Avanza's effect is nothing but sedation for the first 15 mins. That's all. it doesn't brighten my mood at all.
Strangely, it's reputed as being a nootropic, if not mistaken i read it in Wikipedia. ( I am taking the SolTab, being faster absorbed and eliminated, not leaving the tab sit longer in the stomach. This minimises the sedation/hangover effect).
Here is a useful link.

I find Moclobemide a better mood brightening drug. Just crush it, mix it with little amount of water, and swallow. This give an instant "mood elevating" effect, a slight euphoria. But just don't mix it with any symphatomimetics like Ephedrine, Phenylephrine, or any amphetamine-like drugs. Also avoid mixing it with Pethidine, Meperidine ot serotonin agonists.
I consider Avanza is only good as an antiemetic ( this is how the apetite is increased), hypnotic, antihistamine.
It's effect more or less like Periactin ( Cyproheptadine), an OTC antihistamine, with additional properties used to reverse serotonin syndrome and to increase appetite.
Benadryl ( diphenhydramine) and Seroquel ( Quetiapine) would be very good hypnotic. But seroquel flattens the mood, it's an antipsychotic, that attaches to D2 receptor in the brain only for a short period of time, so it doesn't cause tardive Dyskinesia. I tried both, and would say, Seroquel is several times stronger than Benadryl and Avanza.
