The quest for sleep (getting rid of Ambien and caffeine)

There’s a number of reasons why I seem to have, over the years, developed the inability to fall asleep naturally on my own. In the more recent years I have been able to attribute those reasons to shift work. All the other stresses and issues that could have been a source for sleep depravation from my youth to my adult years I feel I have handled and moved forward from with the last piece in the puzzle being the reliance on Ambien to fall asleep and then again to go back to sleep. About a year ago I tried to give up Ambien an was mildly successful as I recall by using an alternative sleep aid like ibuprofen pm but was having to take too much and feeling too groggy as a result so I gave it up. About three weeks ago I started the journey again. During my time off from work (which is 8-9 days) I decided to go without Ambien. This didn’t mean I was getting sleep I was just napping overnight but I was doing ok during the day so I went with it. I also started taking melatonin, 5mg gummies. (They are quite good so I would eat 5-6 of these so about 25-30mg of melatonin). It kind of helped. This week I am trying a new tactic. A friend gave me some hibiscus tea to try. In Grenada we referred to it as sorrel and made a Christmas drink from the hibiscus flowers. I never knew that there is some sleep benefits to this basically from what I’ve read, lower the blood pressure type stuff. It does seem to to be quite relaxing as a hot tea so whether or not it helps with sleep is still to be determined but the relaxing effect...
