I have the impression[1] that there is a continuous, though variable, specific stimulation, which, though no doubt neutral in itself (it is, indeed, disagreeable when observed dispassionately), is a pressing invitation to sensual thoughts. I have never experienced anything like this before.
I wonder, therefore, if you would be good enough to send me a sedative to enable me to sleep at night, and also anything else that you think might be helpful. Sedatives, in the last analysis, are not a final cure for this condition, but they may help to make things easier. The cure is essentially a matter of raising the mind above the waist and keeping it there, but this treatment takes time and is hard work (as you may gather from my letter on drug-addiction).
