I use choline and venlafaxine on a daily basis.

Venlafaxine is perscription only.

I discovered choline when I started getting a new kind of headache. It felt very much like a the kind of hangover you get from swallowing an entire tube of dramamine. (Don't ask how I know how this sort of anticholergenic hangover feels like). I decided I absolutely needed to raise my acetylcholine levels, or else I'd be in trouble soon. So, I found some KMX while looking for something to drink while I was in the drug store. I liked the effect, so I got choline pills after a while, and have been taking them for about a year, now.
