This is just a hypothesis that I've been trying to work out for my friend who has bad PMT (possibly peri) and who is on Studd's regime.
She started out feeling great on 3 pumps of gel, the best she'd felt for years, but after about a month or so she started to feel dreadful with all her symptoms returning with a vengeance. She didn't have to take the Utrogestan for about 2 months and when she finally added this in she felt even worse and had moments of feeling suicidal. When she saw Studd 3 months later he was puzzled by her reaction and suggested she go up to 4 pumps, but she has continued to feel bad but is determined to continue for the remaining couple of months due to the money and time she's already invested.
We were trying to work out what had actually occurred, considering how great she felt at the beginning and now I'm wondering if this makes sense - also for some women on here who have also been struggling with getting the dose right:
If it's a fact that 3-4 pumps will trigger ovaries to stop natural production (like the pill is meant to) to stop any volatility and control things better, and that this occurs after a month or so, perhaps it can create a deficit where 3-4 pumps on top of zero natural oestrogen isn't enough, compared to, say, 1-2 pumps + natural. The Utrogestan will then make things even worse as that lowers circulating oestrogen, which is already too low.
She had tried lowering to 1 or 2 pumps, but only sporadically to see if she felt better for a few days - and nothing changed. This would make sense if it will take at least a month or so for the brain to detect lower levels in order to start to produce its own oestrogen again.
In which case, it may be best for those in this situation to try going back down to 1 or 2 pumps for over a month to see if this allows ovarian production to restart (or stop if for a month to let everything reset and then just try 1 or 2 pumps). I suspect, upping to 6 pumps might achieve the safe but surely our own oestrogen will feel better than the external stuff - even if natural.
Anyway, just wanted to share this in case it makes sense to anyone else who is having problems with the dose and also finding the maths don't add up.
