"i can&#039;t remember the exact dose but it was low. it caused insomnia (4 hours sleep a night), feelings of giddiness and weight loss (14lb/1 stone) which was a positive for me. because of the insomnia i came off it and was put on 25g amitriptyline. with this medication i have 9 - 10 hours sleep, dry mouth and a huge increase in appetite for sugar and carbs. but my depression seems to be a bit elevated."
