Getting off the couch

After leaving the military on 2006, I have tried to stay in shape because of my grand-kids and just because the human body needs to be active.
I am 58 years old and I have PTSD, high cholesterol and I cannot sleep.
I was prescribed Amitriptyline for sleep, it had two serious side effects; better than Viagra (but it would knock you out and sleep for a bout 6 hours straight) and the second one was that the morning after I was a total ass-hole.
I was also prescribed Zoloft for my PTSD, so between being an ass-hole and feeling like a zombie it was a no brainer and decided to quit both.
My daily routine was; Wake up, go to work, come home, work out to the point of exhaustion, eat, go to sleep at about 11pm, wake up at 2:30am, read a book or watch the news, go back to sleep at 4;30am, wake up at 5:30am to make coffee and start my day.
I had been to a few doctors asking for treatment for my sleep but all of them were more interested in prescribing me hard core drugs to make me sleep at night. I agreed to get them but never took them. I have a full closet of medications.
The only constant element throughout my sleeping and PTSD struggles was the physical training. I was divorced from my unfaithful first wife and remarried to a very intelligent and amazing new young wife 20 years apart.
Several years ago, my young wife told me about the sleeping benefits of THC.
Now I smoke CBD pens at night (small amounts), sometimes I have an edible and I can sleep for 5 hours straight. Not even getting up to pee.
PTSD dealing factor after CBD....... It makes me more tolerable towards people. I avoid people, I don't like people outside my inner circle which consist of my family and two friends with the same issues I have. Both friends have been to combat, both friends understand what those experiences do to the mind and body. Their wives also understand and help us along the way to recovery and acceptance.
Still I am doing the physical training I was taught in the US Army and understand that your body can do more.
I am retired and driving my young wife crazy as I stay at home 24/7.

I started doing CrossFit about 7 years ago. In all of my travels I have been able to meet people with the same mentality towards physical training (PT) and as such adapt the concepts to my old body.

My yearly culmination of physical success is on Memorial Day; I do The Murph under an hour.
I workout 3-4 times a week not to time limits nor the amount of repetitions, I set goals in calories burnt.
Thanks to an Apple Watch I can track the amount of calories burnt.
Easy day consists of 300 calories.
Hard day (once every two weeks) consists on burning 800 calories. A few weeks ago I was able to push myself for 85+ minutes to 900 calories.

I am going to be posting my workouts if any of you decide to try it out.

JUST FREAKING MOVE!!!!!

If you just started, go for a mile walk three times this week, then the following week you do a mile and add five push ups after 1/4 of a mile, then you add more easy stuff like touching your toes, like mountain climbers, etc.

JUST FREAKING MOVE.

Thanks again for letting me vent.
