I Was On 150g Of Amytriptylene At Night And It

I was on 150g of Amytriptylene at night and it helped my sleeplessness but was feeling tired and morbid during the day. Doc just changed me to 100g of this medication at night and 50g of Citralene in the morning - now takes me longer to fall asleep and still tired in the morning and feelings of morbidity has increased - Been depressed now for over 6 months and feel like I'm never going to get over it! Any recommendations?
