DU I used Amiltriptiline for a few months when H first went, mostly so I could just stop my brain working and sleep, Im not at my best without sleep so didnt want to make things worse.. You can take a very small dose of it as an anti-anxiety drug to help take the edge off things but not knock you out.. Not sure if you can get it in the states worth googling though and it was easy to come off the 20mg when I needed to I just stopped after a couple of nights I realised I hadnt taken it.. but you dont have to come off it slowly at such small doses!
Good luck with him coming back, my H came back because he wanted too but at the same time couldnt afford not too and that is enough of a struggle not really knowing if its me or the money, especially as he wants to be with me but not where we live..
