This does sound stressful, and waiting for the plan is never easy, especially with PTSD.
For Over the Counter options to help support you through this time, or even for long-term support, I suggest looking into Grapefruit and Green Tea. I am a huge Fan of both because they have made me feel like my PTSD is at 5% of what it was 5 years ago, and I am off all my meds because of them.
I drink daily Grapefruit, locally squeezed, and lightly pasteurized, nothing else added. It's wonderful. I sip a 20 oz. all day at work over lots of ice and then when needed in the PM if stressed. Its a blood thinner. I think it essentially replaces naturally something like Clonidine (Catapress) without the negative side effects.
Grapefruit removes harmful, cancer processes in the body. Whatever it does, it calms and lowers my perception of stress in a wonderful way, and I'm so grateful I moved to Florida, just to have access to the juice.
Second, I drink Bigelow Organic Green Tea. It comes in sealed individual envelopes. Other green teas I've tried have a nauseating taste/odor similar to an overly ripe tomato that I assume has to do with oxidation of tannin. Sealed Bigelow, brewed and iced or one bag in a thermos kept hot and sipped at work, is naturally calming and also very good for you
Both green tea and grapefruit prevent several types of cancer. Both offer prevention of obesity and other disease. So it's also a way to practice self-care and self-compassion to heal the effects of long-term PTSD.
They work so well that if I skip a day or two, I start to feel like "I have PTSD again." How much is placebo or real, is indeterminate with both Rx and OTC. But unlike Rx, these two items have 1000 of years of use with no side effects and several good health benefits.
Some people won't like the taste, and I don't if the juice isn't fresh and local, so I know there are capsule forms of grapefruit that some people take for their PTSD with good results. I haven't needed to try that yet.
