MV,I think if you take the Unisom at 9:00 Pm and plan on going to bed by 10:00 PM you will do fine. I am just making a suggestion - only you can decide what dose to take.
I have to comment here re SC's post - she is so kind and wonderful and she phrases her comment so politely - " Interpersonal difficulties are always a trigger for me as well." I am the same as you and SC - knock down, drag out fights cause me high anxiety I couldn't help myself - giggle.
In reality if I have a difficult confrontation with my hubby in the morning it takes me hours to let it go as hurtful things get said even when we don't mean them. Bedtime comes and I find myself crying so practicing forgiveness and letting go are things I need to work on.
I wish you a sound sleep tonight.
