I have insomnia quite bad sometimes, I usually resort to antihistamine tablets but less so since weed has been easily available.
The problem is weed tends to give me paranoia, so been trying to find the best strain.
Gorilla Glue really works well but recently have found Money Maker, zero paranoia and puts me straight to sleep.
You can buy it here, currently out of stock though.
