You might ask your doctor if you can try .5 mg of the Ativan instead of 1 mg. I took .5 mg for panic attack and it worked nicely within about 15 minutes and the sleepiness was held off for several hours. He might want you to take a full mg, so check with him. I don't know about the other drugs.
Imagine, I am hoping you are going to be feeling much better soon, and I think you were very smart to take care of this in the way you did. You are an inspiration!
