Do you have a scale to weigh the oil? The 00 sized gel caps weigh almost exactly 100 mg, so just keep that in mind when weighing out the doses. I would squirt a little from the syringe into the capsule, then barely close the capsule, weigh it, add a little more, weigh it, etc. It gets to the point where 8 out of ten times I can eye-ball it on the first try.
Anyway, just since you're scared, put something like 50-100 mg of oil in the first "test" suppository (so it should weigh a total of 150-200 mg with the weight of the capsule included). Fill the capsule the rest of the way with coconut oil, and insert it until just before the middle knuckle. Then wait. You'll see. There is virtually no effect, and what effect there is, is just a warm happy feeling. My wife has done 1/2 gram suppositories and not felt a thing (with some really POTENT oil).
If you need a cheap, reliable scale, the American Weigh Gemini-20 is only $20, and it's good because it weighs in milligrams, so it's very accurate and you know how much you're taking. I would post the link to Amazon but it's against the forum rules.
About your question regarding absorption, suppositories are supposedly much more efficient than oral dosing. From what I have read, suppositories give you 50-70% absorption while oral ingestion is around 20-30%, and inhalation is around 10-20%. Just make sure you give that capsule at least an hour to dissolve. Try not to poop for two hours afterwards if you can.
If I were you, and I had no way to get my oil tested, I would take 1 gram per day via 3 suppository doses, and, in addition, try tacking 1/4 grains of rice worth multiple times daily and try to work that up to larger tacking doses. Get those capsules ASAP!!! You must get started!! If you can get 50 more grams of oil and stick to this protocol, you might see a major improvement over the next 2 months. I hope you do!
If you're going to primarily be using suppositories, I don't think it matters if you use sativa.
I will tell you this. Neither my wife nor I use sativa very much because it gives us some major anxiety. About 3 years ago, I took a 1/2 grain of rice worth of some STRONG sativa oil I had made. I started having like a major bad trip I was so high in the worst way. I was just trying to survive this terrible feeling of impending doom and this constant barrage of negative thoughts about my past and future.
We were at Disney World walking with a couple of friends in Fort Wilderness. There was a place where some of the staff were rehearsing a play and we were invited in to watch. We went inside and sat at a table in the dark in the back, and I was still having a very hard time, but it was good to be in the dark and in the air conditioning. There were about 50 other people in there watching.
Suddenly, this actor girl tapped me on the shoulder and said "Could you come with me for a minute?" I was so high and in such a bad way that I just blindly went along with her. It was only when we were about halfway to the stage that I realized what was happening, and I debated just making a run for it. They took me backstage behind the curtain with some actors, and they had brought along a few other audience members.
Well, they started explaining to the actor/audience members what they had to do for their parts, and I remember being so high that I couldn't remember what the guy was telling me to do 5 seconds after he had told me. I remember they were trying to be all jolly and make me feel like "this is fun!!!" but I was shaking and in shock, and my mouth was so incredibly dry.
Eventually, they got the part across to me. I was to put on a ballerina outfit, and dance like a ballerina out to this circle in the center of the stage. Then I was to walk slowly to the front of the stage waving goodbye and blowing kisses to the audience. I was the end of the show. I was pretty muscular at the time, so they thought it would be funny to have a buff male in a ballerina outfit. Anyway, luckily I had plenty of practice dancing around at home being silly and imitating my sister when she was taking ballet, so I just gave it my all and did a pretty awesome job. My wife and friends could not believe what they saw. I was shaking for about 2 hours after that.
you have now!
