Hi Peroxiblader,
If you have the extended release ones, try 2 x 1mg and see how you go on. If not, I would just go for 3mg /night. The extended release ones give you a more constant dose throughout the night thus preventing the dreaded wake up at silly-o-clock.
Note: no wine or beer with melatonin, will make you feel really dizzy.
I hope you will feel better!
