Mum and I were chatting the other day and we raised a few questions between us about how much RSO to take. Now my mum is not quite 5' tall and weights about 100lbs, and has never tried cannabis before.
Mum has started of on very very small doses and built her way up slowly over the last 45 days. A couple of times she has tried to double the dose only resulting in her being sick and feeling very poorly. So now she is increasing it at a much slower rate which seem to suit her better. Mum seems happier and not so sluggish and dull even though she has to lie down for a nap a few time a day.

Mum takes more before she goes to sleep at night which gives her a good nights rest.
Mum raised the point of, that in medicine you measure out according to body size and weight, which I also think applies to RSO. There is no way she can take the same amount and her body adapt as fast as say, my dad who is 6'+ and 210lbs.
I think this will take a bit longer than the magic 90 day mark but so far things are looking good. Mum had a CT scan today so I hope they compare it to the very first x-ray and find even the smallest reduction in size of the tumors. If they do I don't think mum will have the chemo but give the RSO a try on its own first.
Mum has also mentioned that she has noticed different looking stuff or particles in her stoma which isn't regular poo. Mum has only started to notice this in the last 7 to 10 days and asked the the question, Do you think that that could be the cancer leaving my body because it has to go some where doesn't it! Now what do you say to that? So we bounced around a few ideas and came to the conclusion that yes it was because to be honest I don't know and wasn't about to tell her anything else.
