Yeah it is, but I really don't want to go down the Opiate route, as I've had/have serious addiction problems when it comes to Opiates/Benzos. Only last week I tried some Oxy for the first time in over 6 Months and 120mg hardly touched me.

Regretfully in the past week I've also been dabbling in Benzos again - Temazepam at doses of around 90-180mg, also Diazepam at doses of 40mg. Although they have taken some edge off my anxiety (Which I know won't last as my tolerance will sky rocket again very soon due to previous EXTREMELY HEAVY Benzo use) they haven't really helped with the Insomnia nor really the headaches. Btw, I went down A&E before I left my home country to get the headaches/eye aches checked out but was given the all clear after extensive testing.
I'm sorry I should have mentioned about the Opiates in my original post.
Thanks for your reply.
