Always baffled me how Pattaya became so popular.
Cities usually spring up from being located on a river which Pattaya hasn't got.
There are hundreds of nicer beaches in Thailand too.
Pattaya just got lucky (or unlucky) i guess.
I used to take 10mg of Amitriptyline but soon found out they would knock a rhino out.A third of pill(3mg) gives me a great nights sleep and at 35 baht for 10 has got to be the best value in Thailand.
Anxiety plus paranoia is an awful disease.
How do i know? Because i've got it.
I suffer from near enough the exact symptoms you do mate.Lucky to have 2 good days on the trot then something really insignificant occurs and the paranoia starts again.
Valium is fantastic but stay well clear unless you have a will of iron and only take one as a last resort.
If you live alone it's twice as bad so try to find a nice lady for company.Exercise,swimming and walking is great too.
I'm an alki to so having a couple of beers in the evening is not an option for me but might work for you.Good luck.
