I had mixed experiences like you when it came to sunshine. Early on it was hard to tolerate, and even to this day my health every year in summer slumps + I lose weight (Im just starting to pick up again now after last 3 mths) Back when I originally crashed with CFS years ago my expsore to the sunshine was pretty good as I used to like to spend plenty of time down the beach, so it didnt do me any favours when it came to preventing me from getting CFS.
About 4 yrs ago though after a big slump from Lyme treatment + over doing it at the gym, I slowly recovered back to the point I could work again and it was from starting out by spending time down the bearch, then doing casual outdoor gardening/painting/house reno jobs, then back to IT office work. My vitamin D levels around this time were at about the 1/3 of the normal range despite being outdoors, however I would wear hat + sunscreen. I think the fresh air and physical movement and having small scale tasks to focus on were also big factors.
I tried to boost my vitamin D levels at one point using capsules (high dose) + vitamin K but my health (espcially brain fog + body inflammation) went downhill for a number of months. When I take vitamin D injection however I dont have any adverse effects but maybe it does not reach high levels when I metabolise it over the 6 months. Its just a shame its so expensive (only cheap if you have osteoporosis).
