Day 4 Roller Coaster

So today is day 4 of taking Lexapro. I know, I know, I have to give it time, and this is only the 4th day. But can anyone tell me if this is what I can expect more of? I know everyone is different, but just curious if this seems normal. I had such a great day yesterday, but a bad night of sleep and worry has left me a mess today. Here is how it has been:

Day 1: Very Little anxiety during the day, but could not sleep much that night. Had those “cool” flashes through neck and arms which freaked me out. They seemed to go along with any worry or anxiety.
Day 2: Had an event so I was anxious about that but the distraction really helped. Anxiety was off and on but low. Slept great.
Day 3: An amazing day. Full of energy with a clear mind. Pretty much no anxiety to speak of all day. Best I felt in a long time. However, woke up in middle of night with the “cool” flashes and worry. Unable to fall back asleep.
Day 4: Feeling wiped and anxious from the beginning. Probably has to do with not sleeping well. It has been pretty much pockets of anxiety and worry peppered all through my day.

Trying hard to keep distracted and hoping that the remainder of day I can turn it around. Maybe some music, exercise, trying to remind myself of how good I felt yesterday and that this blah feeling today is only temporary.

Thank you Rspwed. Those were great words that I needed to hear.

I know that it will get better. Yesterday was a glimpse. And I know this is only the middle of the 4th day. Everyone says the same thing, however, as you are going through it, it is still good to hear, and I still need to talk about it. It is great to hear from others who have been through, and are going through the same thing.

I need to push through today with some exercise, some good music, smile, and just keep my mind on anything but the thoughts in my head.
