I have chronic insomnia. Ambien has stopped working because I've taken it for years. It gradually lost its effectiveness and i had to double up on doses to get a few hours sleep. Then I'd run out of pills whuch was a problem. So I'd substitute with lorazapam. But that stopped working as well. OTC's like dyphenhydramine do not work and actually make me jumpy. Melatonin does not work. All the little protocols, obviously I do, limit caffeine, darken room, etc. Etc. Is there something else I can ask my doctor for? Sleepless in NY.
