Okay, I've read back a little more to remember the details. If I understand correctly you are taking 260 mg/day plus tacking, and taking THC and CBD separately. You are still going through chemo and have a colectomy. Not sure if mid-day doses are sub-lingual or suppository. I understand the evening sub-lingual if you have trouble sleeping, but not the small morning dose unless it's for pain. Finally, still unclear if your goal is mainly to offset chemo side effects, enhance chemo treatment, or to start actively fighting cancer with cco. 260 mg is plenty for 1st two but low for cancer treatment, especially stage 4. Depending on how chemo goes you can make adjustments later.
Changes I would make now:
* Tacking is always a good idea before each dose as a way to prime the system as well as to deliver additional medicine.
* Mix at least a little THC oil with CBD oil and vice versa for each dose. They each make the other more effective but need to be active in your system at the same time. Tacking with one right before you dose with the other would work.
* Are you taking the Apigenin before each dose? 80-100 mg 5x/day is powerful cancer inhibitor in it's own right. Taken 30 minutes before each dose (same amount of apigenin regardless of size of cco dose) will prevent metabolism by liver and make cco far more effective.
* Drink green tea and have mangoes daily (I like dried unsweetened, but any form without added sugar). These keep receptors clean to keep cco working. And dark chocolate (85% or higher).
* If you still have rectum then rectal suppositories will still be effective without the missing colon. This is my preferred delivery method as the most controlled with highest level of bioavailability with least psycho-activity, even over vaginal suppositories. Sublingual doses are taken up quicker but more get metabolized and you risk ingesting some.
It's a lot to keep track of especially on top of chemo regimen, but you're doing great. Keep it up!
