ALL increase my short term memory. (Nothing wrong with my long term)
The Pandora's Box (All I have left until harvest day) has DECREASED my short term memory.... down to a few seconds, in some cases. I mean, I'll literally forget what I'm doing... 5 seconds after I start... often I'll look up and *BAM* I can't remember what I was doing until I look back down.
Indica's are NOT right for my head. There may be sativas in here... but the indica in it is definitely above my tolerance level.
Stay Safe!
